Speed fluctuations and a no care attitude!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

If you would like stable and constant internet speed, rather use a different internet provider. Everything with the speed was perfectly fine until the name and debit order had to be changed from my spouse to mine. We didn't change the location, speed or anything, just the name on the account and debit order details. Since then the speed of our particular line has been fluctuating. I have lodged numerous complaints and checked with the other residents in our street who are using Home-Connect as well. Their speed was not fluctuating, but ours is. It always seems to be the same of day, at night between 19h00 and 22h00. Usually when we are not even streaming anything. Unshaped, unthrottled and uncapped apparently??????? I have requested technicians to come out and assess the connections at our residence and the exchange but was told to just reset the router each time. I am now SICK OF RESETTING MY ROUTER and want this fixed. So my advice to anyone, use someone else! They do not care about service provision.
