Ambrose Electronics Ltd in Abbess Roding, Ongar

I’m from Greece and I would like to inform you regarding to this company that sells cheap mobile phone devices. The name of company is Ambrose Electronics and their electronic address is amnatradeltd.com
I made to them an order for an iPhone 5 16 gb which it's price was 252 Euros. I paid for this in advance, to arrange the shipment immediately as they promised me but the same afternoon, they told me, that because the cost for taxes and insurance was more that they calculated, they sent to the same parcel three more iPhone 5S!!! They asked me to pay for the two of them and offered me the third one for free. When I denied, they told me, that in this case, it was necessary to send them as a guarantee one more deposit, for one iPhone 5s and when I would sent them back these three devices, they would sent me back my money. Of course I did not accept this neither. I asked them many times to send me the tracking number of my order to be sure for the shipment and they refused to give me even this. . They insisted that they will give me the tracking number only if I make the deposit in advance. I had done the first payment via western union and they asked me to do the second payment with the same way, without give them the MTCN number, so I could supposed take my money back after of delivery. Because I didn’t trust their words, I called western union to ask if this is possible and they advised me, to not do any deposit, because this is a usually case of frauds!!! After of that, I called also to DHL courier offices in Greece (because they told me by mail that this was the cooperating courier company) and they confirmed me, that there was no shipment. When I told them my moves, they answered me that the western union’s advice was good… but it was not for them and they told me, that I had to trust them that they would send me my second deposit back, as soon as they get back their rest three devices. They told me also that they didn’t arrange the shipment via DHL because they are not… You can make your conclusions…
Finally, I asked them to cancel the order and send me back my money. Then, their answer was, that because the parcel with devices had reached already in the Greek company courier and remained there for the Weekend, they paid moreover money, which I supposed to debited also, so they told me that they didn't owe me nothing!!!
They insisted with big audacity and rudeness to send them one more deposit to deliver my order. They told me ironically that I do not have any other choice and that the one that will lose if this does not become, it will be me, because I would lose my money.
I explained them that the fault was not mine, because in the case that emerged more expenses for taxes and the insurance, they would simply inform me for these extras (which were 80 Euros) and not arrange to send me three more devices that I never ordered!!! I gave them many possible solutions, but their only answer to my arguments, was their insistence with very bad way, to send them the deposit. Of course I did not make other deposit; however, I lost the money that I had already given to them, because I did never receive the device that I paid for.
I advised of the Greek Police for the case, and they told me that they have official decree of the English police informing them, that they have no intention to check and punish, scams lower value of 4000 pounds. These Frauds know and exploit this. However, police told me, that we (deceived consumers), according to law, we have the right to public protest and protect the others from this scam.

So guys attention!! Don't trust them!! They are frauds and you will lose your money!! Just stay away from them!!

.p.s. i have all the proves of payment and all the conversations for any case!!!
