Mondo MTN Fixed LTE Month to Month Poor Service.

At the end of August, I was contacted by whom I thought was MTN Direct (My True Caller App identified the number as MTN) I wanted the R499 35 Mbps month to month LTE MTN Month to Month package with Free to use Router. I was told the Router and SIM will take up to 10 days to be delivered, however this was not the case. After phoning MTN Customer Care Multiple times and being given different stories I was eventually given the number for Mondo which I phoned now multiple times. I was told they needed proof of payment which was odd cause I paid on their Online Payment portal with my Card, but I did send the proof none the less to the email address I was supp****. Next time I phoned I was told that they have received proof of payment and just waiting for the stock to be allocated for delivery. This Week the 15th of September I phoned again on the Friday and was again told they are still arranging stock and delivery. Tomorrow is the 18th and I have paid upfront for a service I am not receiving. I never had this problem with other Service Providers such as Webafrica. At this point I either want my Router and SIM delivered this week or I want to cancel the Month to Moth contract and get a full refund.
