Poor to no service

My contract with CELL C has ended in November and my account paid up full in November 2021

I have been waiting more than the 48 Hours as advised by Cell C for a contract paid up letter. Reference numbers are ***and ***.

Every time you call the call center and provide your reference number its either an excuse that the system is offline or slow or they need to create a new reference

My credit score is messed up because CELL C hasn't sent this data or paid up letter to Transunion/Experian and every month i still receive invoices saying i owe CELL C R0.00

The service is terrible and as a result I cannot buy anything because of Cell C's lack of competence and to this day is still a problem and no paid up letter!
