DO NOT USE THEM - They have no idea how to bill, They keep sending out incorrect bills. They get more incorrect each month, higher and higher and when you ring they say "oh yes, I can see it is wrong - but I can sort it out" They can't. After speaking to 5 different advisors, all say "oh yes, I can sort it out, the other person didn't do it right, but I can", they took £2,800 by direct debit, even though they said it was wrong and they would stop the direct debit. When I rang, the first person said I would have to wait 4 weeks as they were in the billing period. so I called back, the second one said they were a manager and they would ensure the money was returned within a couple of days . Then had a text message to tell me to contact my bank and use the direct debit guarantee scheme, as they couldn't do it! Then I had a bill saying I owed them £2,200, I went on line and it said £300, which was about right, so I paid £300 and it showed as zero. I then received a final demand for £2,200 and that they would take legal action against me if I didn't pay immediately, oh and then you won't be able to change supplier! When I rang, they said it was my fault for not paying the previous month's bill! I have never been so furious, I am a chartered accountant and can keep on top of what my bills should be, unlike them, their systems are beyond hopless, they should rename themselves Horizon. They had also sent a letter at the same time saying they were repaying me £1,900 at the end of the month. The advisor said I had to pay the £2,200 now and that I would get back £1,900 at the end of the month. Which as they cannot organise a child's tea party (to be polite) I wasn't going to do. I am sure that those who can add up (and therefore don't work for UW) can work out that when I paid the £300 that was really due, I should not have to pay £2,200 nor receive £1,800. After going to speak to her manager she came back and agreed I owed nothing, and there wasn't a credit coming into my account. I am moving to Octopus and informing my MP of this, as I found it very stressful, as an accountant at least I could try and sort it out and knew I was right - this started in the October and was resolved in January. Please, please do not use them, unless you have money to pay their outrageous billing and you like spending your life on the phone to them.
