MTN IS USELESS BEYOND DESCRIPTION!!!!

My contract cell phone stopped receiving calls on the 8th of July. I can make calls, I can send SMSs. I receive some SMSs hours after they have been sent to me! this means I cannot use my internet banking or any other services that require an OTP! This is a business line and I have been struggling with the incompetence of MTN while my livelihood suffers!!!!!! The problem persists with the SIM card in other phones indicating that it is a network and not phone / phone settings issue! The interaction timeline: Called call centre on 10th July to report the problem. The most *********** agent in the world could not answer simple questions and could not assist. She was of NO HELP!

Visited Greenstone MTN and reported the problem again. Was told it is a "strange problem" and that a query had been logged and resolution will take 24 hours. Query ref number "RFQ***"

Visited Greenstone MTN again on Sunday 14th July to inform them that nothing has changed and the 24hours for resolution is long gone. Was told that I need to pay R150 for a sim swap but it is a network issue and it won't help so the query has been re-logged and I need to WAIT 24 HOURS AGAIN!!!!! Guess what 24 hours later, no resolution. Emails to the customer query line- no response!!!! I called the customer line to port my number today and I am told that there is NO QUERY OR NOTES LOGGED AGAINST MY PROFILE!!!!!!!!!!!! I AM ALSO INFORMED THAT I WILL LOSE ALL MINUTES AND DATA REMINING ON MY PROFILE. MTN IS CHARGING ME FOR A SERVICE THAT IS NOT BEING PROVIDED YET I AM SUPPOSED TO PAY AND FORFEIT MY REMAINING BALANCES. I AM PORTING TO ANOTHER NETWORK WITH IMMEDIATE EFFECT!
