Very bad service

I never thought such a huge company could have such poor and disgusting service. After this experience I don't recommend anyone us MTN. I upgraded 4 weeks back through the call centre as they never stop calling you and was promised a certain package. I received the data for that package but not the 200 recurring minutes I was promised I have being trying to sort this out with MTN for the past 4 weeks and after multiple service request with no reselutions as well as the service request been escalated still nothing has been done to fix this. I even spoke to 2 supervisors Charlotte and niyaaz and was told by Charlotte she will contact me personally after 48 hours and never did so and when I call the call centre and ask to speak to those supervisors I am told oh I don't know them there's Noone that works here by that name.and everyone else that told me they would call me back never did. I just get told call back when the ticket is closed or after 48 hours and when I do there's no outcome so they need to escalate the matter. I even ended up sending an email to MTNs complaints departmene and I was told the issue was fixed which it was not I have advised the complaints it's has still not been fixed and I have yet to hear from them 2 weeks later and after all this unhelpful bad service I'm still told I must pay for the full package and full month even after only having half the services I was promised. Never in my life have I experienced such poor and unhelpful service from any company that I have ever dealt with
