Quite simply the worst possible levels of customer service I have ever been unfortunate to endure. I chose this provider mainly due to them being able to match my existing dual fuel deal which was ending with Scottish Power, plus they have their customer service centre here in the North East. When I moved house they could not supply me with gas at my new address, so I moved back to Scottish. Four and a half months after submitting my final meter reads, and closing my account, I am still receiving demands for £4.50 owed on my gas account, even though I am still £53 in credit on my electricity account. Dozens of phone calls and assurances from different staff members later and I am no further forwards, so I contacted their Director of Sales and Customer Services and still no response. To sum up, I am owed approximately £49, and these clowns are potentially damaging my credit rating, chasing me for less than £5. I would never consider dealing with this awful, incompetent collection of amateurs again.
