Poor service and wanting to charge you because they did not do what they should!!

I don’t even want to give them one star. I had a business contract with them and before my contract was due for upgrade I contacted MTN to cancel my contract (in July 2022) my contract was due for upgrade in October 2022. I have cancelled my contract again in Dec 2022 via mail and then telephonically. Then via phone x2. Finally in January 2023 I mailed them again requesting cancellation. And to think I wanted to still use MTN on prepaid…..but definitely will not. Today I got a mail from them stating that they cancelled my contract and that they will be billing me for late cancellation. Because they did not cancel my contract they want to charge me. Poor service……very poor and committing ***** on top of that!
