Jet very bad customer service

Jet customer service is really bad. When they moved over to the new system i had to phone 10 times to get a payment allocated made via eft as every other month. I decided to settle and close the account. After a few emails (some just never answered) and phone calls finally confirmation email received on 8 december 2020 that the account will be closed. Now I see on my credit report the account was not closed and listed as a missed payment. Phoned the call centre and the lady confirmed the account is in closing status and closure overdue. Promised i will receice a settlement letter before end of day which as expected didnt happen. She said I should wait another month for them to sort out their mess with ITC. Worst customer service really!!!
