Not willing to give me a promised rate reduction

On the 14/08/2015 I phoned the *** number and requested a limit increase and a interest rate decrease. I think I spoke to Shaun Solomons since I received the quotation from him. He mentioned that I will not be able to get a better interest rate unless I can prove I can get a better rate some ware else. <br> <br> On reviewing the quotation I noticed that the interest rate is increase and not the same as provided telephonic ally. I rep**** on the 20/08/2015 with proof of a better rate also querying why the rate was more than provided on phone. On the 22/08/2015 Craig Lang rep**** asking for a full statement for my other credit card and I supp**** it on the 24/08/2015 with reference number CRM:***. Since then I have not received any feedback and again asked for feedback on the 31/08/2015.<br> <br> Up to today I have not received any feedback or received the promised rate reduction or limit increase.
