Mtn is useliss

In about September 2022 i tried to get MTN to remove an e-sim watch from my profile because they cannot port my number to a bussiness contract with an active e-sim. After many calls and visits to 3 different stores they finally managed to remove the e-sim but they also managed to de activate my number for calls, so now i cannot make or receive calls but my data and sms service works. I then went back to the stores but its only empty promises then i went to Facebook with MTN South Africa October 2022 and they are brilliant and asuures me they will work on it. Needless to say thats where it ends and they do nothing and every time i speak to them its a different operator with the same useliss message that they have escilated. 3 days ago i send a message with a new number i have to use so they can phane me and offcourse they dont phone me. I have 2 Bussiness accounts and personal but they refuse to give me service. About 15 years loyal to them and this is how i get treated, you know if something goes that bad that a number is lost why not tell the customer so you dont sit like a fool waiting and paying for nothing
