Shocking service

Absolutely appalling customer service. They experienced a billing problem this year where they did not debit my account. They listed me as a late payer for three months in a row and then triple debited me with out any communication. I called to complain on many occasions was given a reference number twice and even exculated the complaint with no response back. This has affected my credit rating. I am so disgusted as I have never missed a payment in my life on any account. I actually feel sick to my stomach having to go through the above! The first time I called to ask what was going on they apologized as it was a billing problem affecting many of their customers I had no clue they had put as a late payer.
