Restarting router multiple times a day

Good Day What is going on with my service? Every single day I have to restart the router every hour at least. Your support says its with your engineers but I do not get any feed back. Every day especially after 1AM my ping is too high. I need this fixed without any further delay. Also when I made an extra payment it took over a week for the payment to be allocated. Please stop dragging your feet and get on with it. For R999PM I expect better service than this.
