Unhappy customer

I am back again here for the 3rd time with the same issue from Telkom. My wifi again hasn't been working since Sunday the 3rd of October and I had to make other arrangements for work as I work from home and I need comprehensively working wifi to be able to do my job. No one has contacted me. I am at a position where I am forced to cancel my contract with them. This has been happening every month for the past 4 to 5 months. I am so unhappy with Telkom. To think that I have been with them for the past 20 years.
