HELLOO MTN...WHERE ARE YOU!!??? CONTINUOUS MTN INCORRECT USSD AIRTIME BALANCES & ERRONEOUS INSUFFICIENT AIRTIME MESSAGES

I have alerted MTN to the constant and ongoing issues I have been experiencing with my pre-paid MTN data and airtime over several months now and although MTN (via Kabelo Brett Mosimanyane - Complaints Analyst) has promised to "contact (me) soon to discuss the matter and get a solution", it is over 2 weeks from my initial complaint (however please note the MTN issue has been going on much much longer!!!!!) and I haven't even heard a whisper from MTN. They have disappeared like SA funds into a Gupta-linked company bank account!

Here is the issue: The MTN voice and USSD service are giving constant erroneous messages! I am being told I have no airtime when I do in fact have airtime. This issue "magically" disappears when I reboot my phone and my disappearing airtime "magically" re-appears again!!

I complained to MTN on this forum on 20 September 2017 and then again yesterday morning as I have still not received any feedback. The issue also surfaced yesterday morning!

Guess what!? ... this error occurred again yesterday afternoon, so I wrote another complaint about it on this forum with screenshot evidence of the MTN error. And guess again!? ... this error occurred again this morning!!

At 07:22 this morning, I get an insufficient airtime message and my USSD balance reads R0 and yet one minute alater at 07:23 after rebooting my phone , I magically have R37.16 airtime. WHAT IS GOING ON HERE, MTN!!!??

How many complaints must I write before someone has the decency to respond!!?? I told you this was happening almost daily and there's your evidence. 3 times in 2 days and still counting....

HELLLOOOO MTN...is anyone actually out there!!???

Can someone please: (1) have the decency to respond? (2) MAKE A PLAN TO FIX THIS ONGOING MTN ERROR!!!

THIS IS BEYOND RIDICULOUS!!!
