Signal loss for an hour each day!

I have been a Telkom Mobile customer for over ten years. Overall I have been fairly satisfied with their service. There was a period when their signal was very poor and since then there's a notice when buying LTE data bundles to make sure that you have coverage in your area, which I do. recently I bought an Off Peak hours Uncapped bundle which is active from 12am to 7pm. The problem I have is that almost every day, for about an hour during off peak, I lose signal. I would like to work from home and that's part of why I bought this bundle, but almost every day I lose signal in my home for about an hour and then I have to keep checking for signal the whole time. I'm already only able to use it for a certain period of the day and then I still lose signal for a portion of each day. I feel cheated by Telkom for their poor service and network.
