BAD SERVICE FROM NEOTEL - DON'T USE THEM

A Rep came and see me in Dec and sold a new contract to me (rooter /data) When I received the rooter nobody at neotel could get it to work. I cancelled the contract within 7 days - and since then I received an account from them for the new as well as the old service - which I'm trying to get credited since Dec. They told me they will send somebody to collect the devices - which they only did on Friday 4 March - 2 months later - AND they told me they can't finalize or credit my account until they get the rooter back. Today I received a phone call from a debt collectors they handed me over. You can't speak to anybody who can help you. They only send email's and If you ask why can't they phone you when you send email's they told me they only read email's when somebody phone in then they look at the email's. I don't know what to do any more. I send almost 30 emails to them already without the times I phoned. My first ref nr: SREQ *** / LATEST SREQ*** If somebody can help me I would appreciate it
