No data connection MTN BAD SERVICE!

This is my last resort, it seems no one in MTN can help or is willing to help.

I upgraded to a new Samsung S8 + on 2 October 2017, which included the 10Gb data bundle for 3 months. First month went fine with no problems. On the day my bundles were supposed to refresh I received the sms that my bundles were allocated and checked my balances using *141#. My data balance showed as 5Gb available. So I thought I would wait a day seeing that I did not get the 10Gb promo bundle and my 1Gb contract bundle. Next day I checked balance again and it was still on 5GB. Then I noticed that I cannot use anything that requires data on my phone anymore, Ie. WhatsApp, Waze, Internet browsing. Which obviously means I do not have data available ?? Doing a new balance request, it shows I have 3.9Gb available??

I have emailed MTN Support, with no response. I have Twittered MTN Support with no response. I have been to 2 MTN shops where they reset my phone 20 times, removed the sim card 10 times, redone the APN settings 5 times, changes sim cards from their phones to mine etc with no luck. They phoned several support people, which are not helpful at all.

I even spoke to someone at 808 which also was not capable of helping and did not really care. I bought a new 100Mb data bundle, and my data balance is nou on 4GB, but I can still not use any data!!

MTN your service really suck!!
