Poor signal

The signal in our area has been getting worse over time, we used to have Late service inside, now we have no signal, when going outside, you have to walk around the premises to try and find signal. I have logged a service complaint, I did miss their call, and had to log another service request. Still waiting for assistance. Some of my friends and family members have moved to MTN and Cell C and they are happy with the coverage and service. Kindly can you work on solving your coverage problems.
