I bought a phone last week from the Carphone Warehouse on a 24 month contract. However I'm not happy with my monthly data allowance (250mb) and I went on their website and after looking at their deals on my phone and network provider, they offer a deal with the same minutes and text allowance but higher (350mb) data allowance...for the price I'm paying. I can't see my deal anywhere. I obviously asked the salesperson for the best deal, and I feel as though I've been shafted. Do I have a right to complain and demand my data allowance be upped to 350mb?
