Poor coverage of cell C

Good day

I’ve been experiencing poor reception for some time now. I’m unable to get reception/good coverage at home. I have complained about this last year and was told that if by July 2018 it wasn’t resolved, my contract would be canceled free of charge.

Luckily it was resolved, but over the past 2-3months it has been shocking again, it’s finally got out of hand now, I’m having to wait for minutes on end and there is nothing happening. Slow connection if I’m lucky. This is getting quite frustrating as I’m unable to do any work properly at home.

Please may you assist me, as this problem is it getting better, and I’ve been very patient, you may have a look at the records and see that I have complained/brought this to your attention in the past.

The sim contract in question is:(074) **********
