BCM billing 2 people for the same property - Highly *******!

I have been trying for almost 3 years to get a water account sorted out for a property I sold and was registered in the new owners name in the KWT deeds office on the 15th November 2016. After numerous visits to BCM, phone calls to people supplying all relevant documents, I am still receiving a monthly account. I have been handed over and I have since supp**** all documentation to the attorney who in turn sent it straight back to BCM and I still do not have anyone communicating with me! If this affects my credit rating I will be highly upset as the issue at hand is total incompetence of BCM staff. My account has always been paid on time. BCM continue to bill me for a property I do not own and better...they now bill the new owner as well. How convenient to bill 2 people for the same property. That is "*****" I would say.
