Bad service and dishonesty

This company I have been trying to get an installation only to find out they registered my address to my other neighbour now I'm asked to give my proof of address when Im the one residing in this address but already my address is in use by my neighbour I can't get installation they even gave me reference *** looks like it's even invalid everything they doing isn't assisting me I've been sent around and not assisted because of their negligence regarding my address why they didnt ask for proof of payment from the person who is currently using my address now o dont have installation because of my address issue
