Network coverage is worse than your terrible service

Logged a query via ********** 212 on 21 Nov - reference ********** . 3 times every week, since then, I've been attempting to engage with the (3rd party) outsourced tech team which MTN allocated to the case. I have found that they right out LIE on their feedback "reports" to MTN - stating that they make attempts to call me, but that I don't answer my phone, etc. Meanwhile, the truth of the matter is that they have botched two site visits... they have "attempted to improve signal" by doing absolutely nothing... and Benson now tells me that "nothing more can be done to get what I want". What I WANT, is an improvement on my data signal, from the THREE towers that service me in this JHB metro area!! I think that the 100GB that I pay R3000 per month for on my contract & service fees, should cover at least once decent effort to correct the dead spot here (affecting many other MTN subscribers). I was told 3 weeks ago (Benson, again) that installing a signal booster is a "last resort" ... I've had this same issue in the past (I've been a loyal client for 15 years), and it was resolved speedily, and professionally. Why must service levels regress EVRYWHERE, these days? Why can't MTN act their part and IMPROVE the service which we pay top dollar for? Why is the attitude in your call center (Kagiso), SO poor? Your representatives act like they get paid to show up, with absolutely no regard for the frustration which clients go through week, after week, after week! It's pathetic, really. Leaves one with little choice but to cancel and opt for the SP that actually offers a signal at my house.
