Hopeless

I have Wifi contract with Telkom until May 2023. I am so unhappy with them. Every time loadshedding starts, Wifi lasts only about 45 minutes then it disappear until about 10min after loadshedding. I pay to have Wifi, but during loadshedding I have only 45min to can use Wifi. This is not right, I don't get what I pay for. There is also no way to can give them a call. I went to Telkom in a mall, and they not bothered, just said can't help me with the problem. All other providers don't have this problem, only Telkom, it does not make any sense, I want this problem sorted. I live in Stilbaai West. Not happy at all with Telkom very bad service.
