Afrihost unacceptable returns policy on new hardware and general bad service

I signed up for Afrihost Fibre

Within 2 days of receiving the Afrihost provided router it was determined (after approximately 4 hours on the Afrihost helpline) that the fault is extremely likely to be with the router.

Given Afrihosts' own return policy on 'device warrantly and refund policy' which states in section 1.1 of the General Terms that "Afrihost has a 7-day device return policy. Devices can be returned for any reason during this period" I was surprised to hear from the Afrihost call centre assistant that I was required to return the device to Afrihost so that they could perform 'testing' to determine whether or not there was a fault with the device.

To add insult to injury I received an invoice amounting to R99 from Afrihost for the courier fee to collect the device. It was never explained to me that I would receive an upfront invoice for courier collection prior to me receiving the invoice

I have no issue with paying for a device that I have arguably damaged. However what I find to be unacceptable is that I have to pay Afrihost to test a brand new device that never appeared to work
