Complaint Slow Internet Connection Ever

I am quite disturbed with the manner in which SADV conducts their supports services. I have signed up in mid May 2020, to be honest with that is the last 2 weeks I have ever had good connection. I have been sending emails to the support email address and no response at all. Not a phone call The last email I have sent was last week the 25th Jul not even a response but they are very fast to access my bank account for a debit order. I am starting to believe that I am just doing a donation to the company monthly since I am not getting value for my money. FT Sawula 1 Victoria Close
