BAD customer service MTN

I have experienced thee worst customer service from MTN. As a loyal subscriber to the network since cell phones came to be, MTN's customer service are this time was appalling. My phone was ****** a week ago, and I have been trying to get a sim swap done for Pay as You Go card for 7 days.

I bought new sim, tried self help service 6 times, and got SMS back to call 135 since sim swap could not be done. Called 135, who asked me a whole buch of stupid questions, to which they say I failed 3 times and sim swap cannot be done. I asked what my other options were. They advised to go to MTN store with affidavit and certified ID copy, which I did day 4 after phone was ******. The lady at the store said she cannot do it since the system has been changed. They only deal with contracts anyway, but she will scan documents in and escalate. She assured me it will be done in 2-24 hours. I call 135 to follow up after 24 hours. The cc agent says it has not been done, I should call back in 2 hours as it is sitting with supervisor. I asked to speak to supervisor or manager. The agent refused to hand the phone over and made an excuse that she does not who the supervisor is and only see a user ID. I call 2 hours later to no avail. It is Monday 09/12/2019 today, 1 week later. I acll 135 to follow up. The lady tells me she does not pick up any sim swap request. after a lot of to and fro, she admits there is an affidavit attached no ID. I need to go back to MTN store to scan in my ID as well. She gave me her email address *** Went to store asked for them to scan it. the lady there Thembi asks if I have a ref number. She cannot see any request, this without even asking for my number or anything else to help her find request. eventually Thembi scans it in... Will await and see if this swap will be done...finger and toes crossed. IF NOT...Goodbye MTN, for good. And I will spread the word and convince people to go with any other network BUT you! Wow MTN wow....really?
