MetroFibre poor communication and poor service

I recently joined MetroFibre and im having the worst experience. Firstly after a hard and long fight it took them 8 to 9 working days to install and activate Wifi in my place, An agreement was made between me and MetroFibre that the monthly installment will be debited from account on the 1st day of every month, they have send me 2 different invoices with different amounts and failed to advise which one is valid, I did Liaise with the finance team and the agent who activated my acount and did not receive any joy, still no amount has been debited from my account. Their communication is poor, they cant answer my questions nor can they do the effort to give me a call after I demanded to speak to a manager. MetroFibre has poor service and the communication skills are worse!!
