On Air the worst purchase I`ve ever made.

For two years On Air have been trying to bill me for two explorers and from the offset I`ve informed them that I only received one Explorer. Now after 2 years I`m receiving calls from Affinity Debt Management claiming, I still owe R3356.70 and when you try and call them, your calls are never answered. Oh and when Affinity Debt Management calls you, they only let your phone ring once and that is followed by an email and a text message. When you reply to the email, you get no response. On Air and Affinity Debt Management get your business sorted and stop harassing me for your errors.
