Services Suspended

From the 24 March 2016 after paying our account, services are being disconnected weekly, i have spoken to and emailed a number of consultants and again last night services were cut. They are not resolving the issue upon my many calls explaining the same story and no of them have sorted nor fixed anything. Payment was made using the incorrect ref nr and i have explained telephonically and over email and none of + - 10 consultants have sorted this problem out. i sent a email with a formal complaint and no one has even had the decency of replying. they are all ***********, lazy and treat people according to their race. despite my many calls and emails nothing has been done, i was even told by one of their call centre agents she cannot help me because she is knocking off work.
