MWEB IS ABSOLUTELY USELESS

We have been trying for two months to change our account number from which the debit order is deducted. Last month we were disconnected for non payment as they processed the debit order on the old account. After holding on for absolute ages for their customer care I confirmed the new account number. WE HAVE NOW JUST BEEN DISCONNECTED AGAIN for non payment!!!!!!!!!!!! Benn holding on for customer care for 26 minutes!!!!!!! What is so difficult about changing an account number. VERY DISAPPOINTED IN MWEB AND VERY POOR SHOW. ONE STAR IS LESS THAT WHAT I WOULD GIVE THEM BUT THERE IS NO OTHER OPTION. CONSIDERING CHNAGING OUR SERVICE PROVIDER IF THEY DON'T JACK UP THEIR SERVICE!!!!!!!!!!!!!!!!!!
