Telkom All hour Unlimited data for 30 days not working

I bought Telkom data Unlimited All hours 30days bundle for R629 which is usually working for 30 days as i started using it since July. July and August I was happy. Mid September problems started it was working until 18:00 then stop till next morning 06:00. We couldn't connect at all. When I logged the case ***7, the called for 2 weeks not even knowing what to say cz we tried to Reset to default but nothing. They say it's peak hour or Tower. All sorts of excuses. My son is using Telkom contract n is connected. Which tower is he using? My neighbors are using Telkom and they connected. For 2 weeks I've been waiting for solution. Bcz of frustration I Topup again for R629 but still there's no data. I called this morning bt call centre can not help. This I daylight ******* by Telkom. They can't even analyze the data usage. They have no answers. What must I do I want my R629 to be credited
