After receiving poor customer service, which involved overcharging and not answering my emails or a letter to the CEO I was offered the faster service for the price of the 500mbps. When that happened my landline stopped working. After hours spent on the useless live chat and waiting an age to speak to someone on the phone nothing happened for 6 days. Eventually the landline worked. I received an email saying an engineer would visit on the 8th, that never happened and I was promised a call back on Monday that did not happen. Nearly all my emails went unanswered.
