No contract signed. No service rendered. Billed for cancellation.

NO CONTRACT WAS SIGNED. NO SERVICE WAS RENDERED. people came to our house saying they work for vox. we told them we are interested on fibre and gave them our details including banking details and ID. For weeks there was no communication from them. We had to be the ones initiating communication and it wasn’t professional on their side. Months go by and fibre is still not installed. We had to tell them to cancel the installation and now we are being charged 2K and now suddenly it’s 3K FOR SERVICE NOT RENDERED. They are even invoicing us for February but never bothered to come and install fibre for us. I will be taking this up with ICASA, Consumer Goods and Services Ombudsman, and National Consumer Commission. We cannot pay for no service and poor to no communication. Show me the contract with my signature that you say I signed.
