Bad bad mediocre service

I received my 5G router mid March just before quarantine because I had to work from home the router worked well for a week now it sporadically works I reported the issue and they said they’re looking into it to later give me feedback that there is a problem with the tower in my area they are going to fix it later to follow up on the issue to be told that it hasn’t been fixed they did some escalation and ended up sending a technician to my house but they couldn’t resolve it they found out that my WiFi router is connecting to a tower that is in the Northern Cape when I’m in centurion and there’s is a tower within a 5 km radius from my house

Now they no longer giving me updates I’m struggling daily with the connection and when I log calls I’m no longer getting any response I’m just stuck with their router and I think it would be best that if they are failing they just come take their 5G router and stop charging me for bad service cause this is just utter ******* as I need constant internet connection to perform my work requirement
