If I could give Rebel - a UK utilities company that is now in administration - a negative rating then I absolutely would.

The company's so-called customer service team has been haranging me to pay a SECOND final bill of £120 despite the fact I already paid a final bill in April.

Even though I have sent them payment receipts and evidenced meter reads, and received corroboration from British Gas, Rebel has insisted I pay them their outlandish second bill.

Their most recent reaction has been to set a collections company on me because I dared to challenge their obstinance. They have also completely ignored my requests to make an official complaint.

To make matters even worse, they have just emailed me to say they intend to re-bill me AGAIN, thereby starting the whole bureaucratic nightmare all over again!

Honestly, dealing with Rebel's customer-facing agents is like banging your head against a brick wall.

Quite simply, this has been the most inept and most stressful customer service experience I have ever encountered with any company, utilities or otherwise.
