I did call them many times regarding my slow speed issues, they asked me to reset the router and I did so but having the same problem. they said they can't improve my speed even I am supposed to have 100mbps and now having between 2mbps to 20mbps the speed is up and down all the time. I also did request with them to send an engineer at home when convenient and fix the issue but they refused to do so saying they can not see their device fault. Then I told them I am not happy with the service and request to cancel my contract but they said I have to pay early termination charge. I am suffering from the last five months with this issue and facing mental torcher. Thank you.
