Appalling service from Incredible Connection after buying a faulty printer.

I recently bought an HP Smart Tank 750 Printer/copier/scanner from the branch in George. Within 5 weeks, the printer no longer worked. I returned it to the Knysna Branch who sent it away for repairs. I was not offered a refund/replacement or the option of the repair. After 6 weeks of being inconvenienced they returned the printer to me, only to find that after it printed once, it ceased to print again. I have now taken it back to them again, and they now refuse to give me a refund because I no longer have the original packaging. This has now almost been going on for 2 months, and every time I need to have something printed I need to drive into town to get it printed elsewhere, all while they sit with my money and printer. Incredible Connection Head office hasn't even responded to my emails. This is ridiculous and I will NEVER support Incredible Connection again, especially after the appalling service I have had from them.
