Paragon Square Burgers and Kebabs in Hull

Place was good until one time I came in I ordered a doner kebabs and notice that one of the strip of kebab was coloured orange. I thought that it will be crunchy or something so I ate it but it has a sour taste in it. I knew it was out of date or something, it tasted like when milk is out of date the sourness in it. Urgh.
In addition, I came in before and asked for a sauce to be put on top of my pizza but they said I had to pay extra 40p for sauce. However not even 2 weeks ago I was there and asked for the same sauce and they gave me it for free. I told them this and even asked him to tell the person that served me. Sadly that person denied serving me. Really bad customer service. Not happy.
