PNC Bank N.A. Credit Card Complaint

PNC Bank N.A. Credit card department,

APR or interest rate Pennsylvania

Was offered a credit card from my current bank, PNC, -/-/-. The offer was 0 % interest until -/-/- and 0 % on balance transfers as well. Then an APR would apply after that date. I applied for the card and was approved ; talked to someone on the phone during this process and they confirmed the terms of the card. I transferred a rather large balance ( which I paid a fee for ), then used the card for some purchases. And now they are charging me interest on the those purchases!! I called PNC and they insist they did not send me an offer to what I described - which I know for a fact they did. I have - banking accounts with PNC and have been a customer for 30 years, before they were even PNC Bank. I absolutely would not have opened this card - the card I was using before I opened this one had a lower rate than what they are now charging me. The ONLY reason I did it was because of the 0 % on purchases. VERY unhappy with this situation.
