Horrible service provider

Worst service provider. I app**** for their wifi on the 16th December 2023 I paid everything and they told me that they will come and install on the 4th January 2024, they didn't come I called them and came with stories that the people who must come and install are not back from their December holidays they will come on the 5th December. They came and installed everything, but after a day I struggled to connect to the wifi coz it's on and off last week Thursday I I couldn't connect at all till today. I call their call center on Saturday 20 January it took them 30 minutes to pick up my call, when they did pick up they couldn't even help they said I must switch off the router and remove the cable and put everything back together which I did everything they said I must do but still couldn't connect . Then I spoke to them via whatssapp they told me the I must do same thing I was told when I called them still nothing happened, then they said they will send their technician in 48 hours to check it for me that was on the 20 January 2024. Wednesday I sent whatssapp at 13:00 asking when are they coming and they responded to me at 16:44 telling me that my name it's in the list and they will send someone. Today Frida 26 January 2024 I sent them a whatssapp again at 09:54 I sent a whatssapp asking when are they sending their people, till now 11:17 no respond from them. I regret signing up to their product I paid full amount on the service but I only used it for a week and even on that week the connection was bad and now I have to pay again for something that's not working
