incorrect bill

So i asked for a relocation because i bought a house, and i also bought a business line for my sister because we work from home. so now i get an invoice that i owe R11677.45 , i did not ask for the Nokia router, my router was working fine. i have 2 routers and home i can not pay what i did not buy, i asked the guy that came to install it why are the changing the router he then said its the new ones they are using now, look i did not ask for this i only change my speed to 20Mbps nothing else.

it took the whole month for vodacom to deliver my second contract because people didn't know what they were doing. an d i cannot be held accountable for something i did not ask for

i escalated the mater to the CEO but still was not sorted, even the CEO has bad service i will never buy anything from Vodacom, i recently started a new job as and accounts payable manger and my company wanted to buy me a vodacom contract and said hell NO
