DELAYING TO CLEAR ADVERSE ITC REPORT

I've requested closure of my Discovery Credit & Transact since they refused to reactivate it after I settling it. Since I had positive balance they requested banking details so that they could do a transfer for which I've sent 2 weeks ago. They again requested that I convert my Miles to cash so that they can also do an EFT. After converting my Miles I decided to personally pay them to my bank account as I've already knew they would take forever to transfer and close the account. The reason I'm pushing for account closure is to ensure they issue a letter of good standing so that my ITC is updated and it seems they are not interested or they are using delaying tactics so that I can pay transact fees again this month
