Sales consultant eager for a sell

I was called by an agent selling me an upgrade on my current package (router). He told me that they will send me the latest device since mine is the old 1. I agreed thinking it's just an upgrade not a new contract Only 2 my suprise I receive a billing statement stating that I have 2 devices that render the same service at 1 household. What will I be doing with two routers which do the same thing? I sent emails called and no1 has gotten back to me

Calls are recorded there is a recording of me asking the consultant if I will be debited twice and he said no, I really do not need a second contact, I haven't even used the new router

Only thing I Got is a Reference RCO 581889

Iv been calling and emailing but I don't get any response

I'm really disappointed on the sales agent
