MTN Poor Customer Service

Disappointed by incredibly poor customer service from MTN. Brand new router taken out with a data contract less than 2 months ago has been problematic from the beginning. I could not return during the first 7 days (but did advise the technician during this period) and thus did not qualify for an immediate replacement. Device was sent to the assessment/repair centre and almost 4 weeks later it has still not been assessed. I'm paying for a contract for which I am receiving no benefit. With no router I am forced to buy addidtional data for my cell phone which is being used as a hotspot.
