Pathetic service from Prepaid meters

Been trying to sort out change of ownership of the prepaid meter due to the property being sold since late February/March - it has been an unnecessary nightmare!!! Both new owner and myself were angry and frustrated at the length of time , countless emails sent to try and get this resolved. My simple requests have also been ignored - one being to pay the new owner March's amount - even after submitting 3 authorisations via email & telephonically it did not happen and the new owner had to contact me AGAIN. I then 2 days ago asked for the exact amounts paid into my account to be sent to me (I have 2 other properties on the system so didn't want to get amount wrong and also wanted new owner to have comfort I was paying him the right amount) but I get an email asking me to fill out a form to register. I mean do these people follow a thread of correspondence at all and do they know what they doing? I'm fed up!! We near the end of April and both the new owner's and my issue remain unresolved
