Bad Service

Good Day

I purchased a 12 Month Xbox Live Gold subscription at BT Games Cresta. When I entered the code it only activated 3 Months, I went back to complain and I spoke with management which they then told me they could cross reference it and on checking they activated the wrong subscription as there was a 3 Month purchased the same day with a console. They then said unfortunately that they could not give me a new one or refund because they needed the code, even though i had a full bank statement provided to them.
