MTN network coverage problems not been rectified

Since the 12th of April 2021 I'm encountering total signal loss on my phone and wi-fi router almost daily for periods ranging from a few minutes to a hour plus. Before that my signal reception was excellent. On 30th of April the matter were reported to MTN Network Coverage Problems. I've been informed that they are aware of the problem in the area I'm living in. On 13th of this month I reported again this problem and received the same feedback. This situation are really troublesome for quite a few times I were busy with phone calls or internet and the signal completely cuts off. Then I must revert to my wife's phone to finish this conversations. I'm really disappointed in this service from MTN because previously I was very happy with services rendered. Currently I'm considering not to renew my contract which has expired earlier this month due to this problem for I don't want to bound me with a new contract and then encounter signal problems the whole time.
