Uncapped Home Internet Router Faulty on Receipt and not replaced.

Please see attached copy of SMS.

I subscribed to the MTN Home Uncapped @ R 399/month via Mondo. The router and simcard were delivered, but, after numerous calls, I was told to return the router to my nearest store ( Beacon Bay, East London ), as it was not working. This was done and the router was sent away. I received an SMS, and I called the number. I was told to go to Beacon Bay store and to tell them to contact the number provided - This was to supply the store with a credit note number and to verify my ID, then I would be given a new Router. After 2 visits to the store, I was told that they could not supply me with a new router, and they also refused to contact Mondo. I had to pay upfront for this month to month internet, but yet to receive my router. PLEASE treat this as a matter of urgency. My details are : Lance de Jongh *** ID :***

Thanking you in anticipation of a speedy response.
