Bad service Too much wifi

I have been having connection issues for months now I wrote emails made calls logged tickets but they only fix it for 3 days then back to square one. I'm tired of Too much wifi the don't deliver service at all.They are quick to remind for payment for something that is not working. It's always the technicians are working on it,on what fix problem for 3 days 😒 Even their consultants know nothing they close the ticket without fixing the problem then you have to start all over again
