MTN ****ing SME's faster than the Coronavirus

Since moving to our new business property 1 Feb 2020, we have had no signal. Dropped calls, no internet access and NO help from the Call Center agents. Logged an enquiry 4 Feb 2020 with ref *** and every time I call to follow up, i keep getting told someone will call me, Still waiting. They have scheduled an appointment at my property 17 March 2020 and didn't pitch, no call or explanation. they also refuse to cancel my contract without me having to pay penalty fees. so my ONLY choice is to continue paying for a service i do not get. hows that for treating customers fairly. R3800 monthly for no internet access ( so i have loads of data ) and my minutes are depleting at a rapid rate, up to call 8 attempts,, calls drop I have to call them back and yet I am charged per minute and never had a single conversation. The last feedback is that there is an issue with the tower in my area feeding me signal, no plans to fix it. What do I do now?
