Paid up letter.

My Old Mutual accounts were handed over to Shapiro but I am not happy with the customer service my accounts are fully paid up but only received one paid letter after making calls.The other account I have been calling to get a paid letter the promised I will get it by the 6th of April today is the 21st and when I call I was told that one of the consultant made a mistake they didn't clear my account and I need to wait another five days.This is very disappointing and unsatisfactory service.
