PATHETIC MTN Customer Service

I have always had coverage problems with regard to MTN cellphone signal at my home even though I live in an urben area. I have called a few times in the past to query this and was always told there is upgrades taking place in my area and the problem will be sorted out in the near future. Having had no joy with this I decided to fill in a coverage related query form online on the 10th of December 2018. I received a responding mail stating that it would take 10 working days for me to receive feedback. Being the festive season I was understanding so I queried again regarding feedback with my issue on the 4th of January 2019 and received a reply on the 7th of January stating that my query was escalated to Themba for assistance. Having still not received any help I queried again on the 14th of January 2019 and to date have not received any feedback. Truly pathetic customer service from MTN. It seems like once they have you locked in a contract they forget all about customer service and blatantly don't bother.
