I am still not able to make outgoing calls

I called in to customer care on Sunday after experiencing difficulty with making outgoing calls which has been an ongoing issue for the last past two weeks, I was given an code to deactivate call forwarding, yet this did not work.. there after I left it thinking it might just be an network issue

I then tried another route and sent customer care an email, after quite a few mails I was told that my number has been reset on the Network, and I should put my phone off and remove my sim card...this did not work

I tried to call in on Monday again the exact same story my number was apparently reset again and I was advised to follow the same instructions and that someone from the tech department will call me back in about 2hrs if the problem persists.... I am still waiting!!!! So I gave up on that

Last night I called in again and let me add I am beyond irritated now, and the woman I spoke to said that my ticket is still open and surprise surprise absolutely nothing has been done no call forwarding or call barring shows on my account

My account is not in arrears and eventhou I am experiencing this issue I will still be billed my full bill at the end of the month

Yet I am still unable to make calls This is unacceptable!

I WANT THIS ISSUE SORTED OUT ASAP! AND ALSO WANT A RESPONSE AS TO WHAT IS ACTUALLY GOING ON!!

THIS WAS THE VERY FIRST ISSUE I HAVE EVER ENCOUNTERED WITH MTN AND I MUST SAY I AM TRULY DISAPPOINTED!!
