Product: Credit card

Barclay card promised a promo rate of 3.99 % of purchases during a time period. The verbiage used initially implies that those purchases made during that time would be forever the rate of what would be needed to be paid back in accrual of the debt. But, in fact, Barclay has the purchases in that promo time go up to their standard rate of 19.24 %. Had I known they would bait and switch like this, I would not have made those purchases with them. I contacted them via online banking first, then another time to their dishonest reply of what was offered in the initial promo offer. I attached for you -- my query to them via inbox of their online banking below. I also contacted a customer service representative and made her promise to take my concern and complaint to the highest authority possible with their company. She did not, I received no additional responses or communication from them to this date. 

the correspondence was this : nterest Rate Why does the promotional rate on purchases of 3.99 % seem to have gotten lumped i XXXX XXXX XX/XX/XXXX, XXXX XXXX  Why does the promotional rate on purchases of 3.99 % seem to have gotten lumped in with the awful rate now? I understand that it is past XXXX XXXX, XXXX, but my understanding was that that rate stays with those purchases made with that rate, otherwise, I would have not done those purchases. It is unethical on Barclay 's part to do this to a customer ( in my opinion ). Please keep these purchase rates separate as was promised.
