No delivery or communication on new router ordered

I placed an order for a new LTE router and the consultant informed me that I would receive the device within 3-5 working days and only start making payments at the end of the following month. I then received a notice from Telkom stating that I could track my order and should expect it within 3-5 working days but when i tried tracking i kept getting an error! Today I called to find out what the problem is and I get informed that I will only receive the router once the first debit order goes through. How am i paying for a device i do not have!!
