Poor business conduct and service

What a shame and extremely poor service with rude consultants, I wonder what Telkom see with this company, This guys sold me a contract of which I changed my mind and returned the phone and sim card within cooling period, 2 months down the line, I'm still being billed by Telkom, when I call telkom to explain, they say I must call sell direct when I call sell direct, they drop my calls. I mean who does that really, My advice out there please deal with the service provider directly if you want a cellphone contract etc, don't give this **** company business, they are *********** and blood sucking ****.
