CREDIT CARD

I spoke to Mpho on nr *** whom is also the reference given on the 24th March requesting that my CC which I paid up in 2013 be closed and updated on ITC as such. I also requested a letter from them confirming that this account is closed and that they would send the relevant info to the bureaus. She was hesitant to write me a letter with excuses but then promised to send me the letter by latest the following day. It is now 07th April, no letter, no updates, nothing. I want my credit profile to be updated as this account should be CLOSED and not just PAID UP. I would appreciate some feedback when this will be done as it adversely affects my credit profile.
