Shocking Service from MTN, notwithstanding their 'champion' consultants

Since my last review re MTN, I have spoken to no less than 6 more supervisors, and since being unable to RECEIVE international sms since my cell upgrade at the end of August, this is the standard response I receive from MTN, over and over and over and over and over and over (am I boring you?, well I have sent 85 emails and spoken to more than 11 supervisors and got the same result): We do apologize for any inconvenienced caused to you. Kindly be advised that this query has been escalated to the business department and they will contact the customer with feedback

They never give feedback, other than the platitude above, and my being unable to RECEIVE international sms has still not been resolved, resulting in my bank account being blocked as I am unable to supply the otp that I am supposed to receive via sms.

Beyond shocking service.
