Bad service and bad connection in the house

I joined them on the 01st October & from Day 1, their connection was very bad & I thought it would change but nooo. To this date, 19 October 2023 I never got helped & all they do is sending me whatsapp of which it doesn’t even help. I called the sales rep for further assist & he promised to escalate but I never got a call from their technicians on fixing the problem and still I’m experiencing bad connection. I would never advise any person about their service or product. My previous wifi was way much better.
