Barclays Credit Card Complaint

Barclays Credit card department,

Advertising and marketing Massachusetts

I signed up for a USAirways - - credit card in -/-/- when they were running a special promotion : Pay the annual fee of $89.00 and receive - companion flight certificates to be used anywhere they fly for $99.00 each. Shortly thereafter, US Airways and - merged and I was sent a letter that they will no longer honor the companion certificates. They did not offer to refund my $89.00 annual fee. They only offered - bonus miles if I spent another $3000.00 on the card in 3 months. The company made good on the - miles, but I just received a promotional mailer stating that they are offering the original deal again : - companion tickets for $99.00 each ... I just spoke with the company and I ca n't get a straight answer. They refuse to discuss the fact that the promo was taken away and now that it is being offered again, they said they could give me $99.00 companion certificates but they would only be good for use in -/-/-. Problem is that we take - vacation per year and already purchased full-price tickets for our -/-/- vacation because we were told they no longer offer the original deal ... Is this even legal?
