2 months for a settlement letter to be sent??

My mtn account was handed over to VVM, account was paid up in November. I contacted VVM on the 7th of December requesting a paid up letter. I was initially advised that this would take 7 days to process. A week goes by & nothing. I called in again only to be told that the turnaround time was wrong & that it would take 21 working days. I called in again on the 13th of January as i still did not receive my letter only to be told again that my request was logged & it would take 7 working days.<br> After speaking to a team leader / supervisor - Marlon pillay, another request was sent to their queries department but up to date i have received no letter. I am appalled at this service. Why does it take so long to draft a simple letter stating that my account has been paid up???? I really dont see why something so simple would take close to 2 months to resolve.
