The service is pretty fast when it works however it goes down more than any other provider I've tried. They increase the price by a few £ every few months and until your 18 or 24 month contract ends you cannot leave. I am currently trying to leave, this began at 4:30pm yesterday, I called their customer service, waited on hold for 25 minutes and was immediately hung up on when I got through. I called again and was given the option to communicate via text, which I selected. I got a text which I replied to, answered a number of questions before being told the conversation had to move to whatsapp, spoke to someone on whatsapp who asked me a load more questions (many of which I had already answered) before being told I would be transferred to someone to deal with my query. After 25 minutes I spoke to a person who asked me a load more questions (many of which I had already answered, sometimes twice) he then said he couldn't deal with my query but would transfer me to someone who could. 17 hours, yes 17 HOURS later I got a reply with another person asking me the same questions yet again. At the end of virtually every message I said please just cancel my contract. He kept offering reductions in prices (despite me previously being told that was not possible) but not anywhere near as cheap as new customer offers. It is currently 10:52am, the person has finally agreed to cancel my contract...in 30 days time.
