Poor support from Jenny's Internet

Our Wi-Fi has been off since beginning August, the technician has come out multiple times and there is no fault with the equipment as stated by him. I have called the support numerous times for assistance and every time it is the same response "Sir give me 20 minutes and I will call you back" and every time I call a different person answers, no call back and no improvement on the speed. I have requested a refund for all the months what we have paid in full and received no renumeration or feedback. Tickets have been opened and closed since August and the problem has not been resolved. This it not the service we pay for.
