FNB HAS NO IDEA OF SERVICE

I am still waiting for FNB to respond to ***** deductions which continued to take place even after a credit card was cancelled. 3 complaint letters have been sent to FNB as well as copies of transcripts. Nobody at FNB can give me a Merchandise Transaction number in order to resolve this query with the party concerned and no assistance has been forthcoming from FNB after 2 months of continuous requests. FNB doesn't know what service means.
