NO TECHNICAL SERVICE

Poorest service ever. I moved from another supplier hoping to get better internet. After there was no improvement in my internet speed I was told I am on a fair usage package and I am being throttled. I upgraded to a faster speed 50/25Mb/s but have been paying for a service I am not getting. My internet is still slow. They have no technical assistance, you have to chat to a robot. I have tried calling the sales department for 2 weeks and every time the person tells me they will escalate it and I will be phoned by someone from the technical department, but no-one contacts me back. Today I asked to speak to a manager or supervisor at the sales and said I am not prepared to wait for a call-back and the lady hung up the phone. I phoned back and told someone else my story and even before I asked for the supervisor she hung up the phone. I am cancelling my contract and finding another supplier!
