Zahir. Absolutely the worst customer service and the worst Internet connection and speed. When you ring the customer services they're an absolute waste of time. Never again will I go with these rip off merchants. When you ring up to tell them that the Internet is slow. They do a check on their side and they say its running on normal. Why then would I get slow speed. I want to cancel because of poor service and they are demanding full payment of 2 year contract. Will be contacting ofgem to complain. If you are thinking of changing to 6g please don't make that mistake as I did you will regret it.
