Non existent service from non bothered consultant

I sent an email to MTN about having no coverage in the area where my office is. THey asked for detailed information, which I supp****, then they asked that I give them 10 working days to reply. At the end of working day 14 (yestyerday), I emailed to ask if anyone was going to provide feedback. I received an email saying that perhaps there might be a tower going up near me but they can't be sure.

How is that service? How could it take 14 working days to deliver such drivel. Is that what MTN deems a service level? Not one contact from a technician or anyone similar to offer advise or see if there's a way to boost signal so that I can receive calls. Just a vague email from MTN. Pathetic service. 25 years as a subscriber and this is the return. Unbelievable but expected in this day and age. Remember the customer? The one's who support you? How about trying to support them? No coverage means my business is under pressure..... Hello. anyone?? Reference number is ***
