MTN the ***est service provider EVER

AbsoluteTERRIBLE service!! I had a contract when MTN opened 7-07-2018, ended 8-07-2020, so contract ended and it was cancelled sucesfully on the cancellation date. No debit the end of July. They still gave me airtime in August, called again, cancelled again, debit went off end of August, cancelled the contract again!! So after all this and being told the number is now prepaid upon loosing my phone 29-09-2020 and trying to blacklist the number,I am then told the number is still on contract, spent all day long on he phone, no soultion, I go into the store 30-09, told they moved over to a new system one is showing a contract number, one is showing prepaid, I fill in some paperwork and the lady sends it away giving me a reference number to use for the case number and insurance purposes. I submit my claim 1-10, the insurance calls me 2-10-2020, the reference is not valid, no blacklisting/ITC number received, I have called MTN everyday for a whole 6 days now, have been given 4 different reference numbers, each time I follow up a few agents cant even pick up the reference numbers, sent emails to complaints department, NOTHING. I have been with MTN now for a long time, my first ever contract, I have had my number for probably more than 6 years now, I will NEVER EVER use the network again, absolutely terrible service, never get to speak to management, nobody knows what they are doing!!!
