MTN does not care about Customer Concerns

I work from home in Moreleta Park, Pretoria. On 14/09/2019 , I started experiencing intermittent cellphone signal problems. I reported this problem on 16/09/2019 (#869384). I was subsequently informed that the site was down, reference no: SMC/***. Was also informed that remote access was done on network tower 8160 Moreleta East VC, and concern should be resolved. I informed Mtn that there was signal for a day,and then it went back to the signal being intermittent. Complained about the concern again on 26/09/2019 (#934753). To date, 15/10/2019, a month later, this situation still exists. This intermittent signal is an absolute major inconvenience to me, as I am unable to use my telephone to conduct business as well as to allow visitors into my estate. Whenever I travel out of the area, the cellphone signal strength is strong and stable. I have been at the same location for the last 19 years, and have been a MTN customer for even longer, and have not experienced such a problem for this length of time previously. If MTN does not have the capability or will to resolve my concern ,that I have been very patient about, they should cancel my contract and refund me for the period that I have an unacceptable level of service. Over and above it all, I always have to initiate communication to determine if anything is being done about my concern. Such a pity that such a large company has such low capabilities and very poor customer service levels. MTN = Pathetic service.
