Telkom LTE is not honest

I have a LTE contract with Telkom, It all started after I got a generator for load shedding. I noticed that during the scheduled load shedding times my Telkom LTE internet will stop working and after load shedding everything will return to normal. After speaking to my neighbor that also have Telkom LTE he confirmed that when our area have load shedding he still has internet connection with Telkom LTE. After numerous calls to Telkom concerning the connection failure during load shedding only on my router, I notified Telkom LTE that I want to cancel my contract. A couple of days later I had full connection during load shedding. This all went well till a week ago. I will lose connection on my router for 2 hour periods per day twice a day. After numerous calls and lies l have to pay for something that I can not use as my internet as my contact stats. What allows Telkom LTE to cut and restore connection to my router as they please and the telling me that they have power outages and when I tel them that my friend 2 km away from me does have internet connection then they change there story. Then they tell me they just restore my connection. Why all the lies. I have to pay for a service that I have to struggle with. I am frustrated and don't know what to do anymore. Please help.
