Online Shopping Nightmare
Be wary of upgrading your MTN contract online as it is not managed by MTN but rather Mondo which is not transparently communicated throughout the process. 

My experience has been over 2 weeks of no communication on my order. MTN customer care are unable to assist at all and refer you to contact Mondo. 

Mondo have zero communication skills or strategy when it comes to dealing with customers. I contacted them multiple times per day for 2 weeks to only be told each time that the MTN system is down so can't assist. Also received promises of call backs that never happen.

Finally after over 2 weeks I am told there is no stock but I am yet to receive any answer as to why Mondo took over 2 weeks to inform me that there is no stock or any expected delivery date. 

I am shocked that this company is trusted to manage online shopping for both MTN and Vodacom. I can only imagine the number of customers MTN and Vodacom are losing due to this non existant customer services. 

I advise anyone to rather use the old fashioned method of walking into a store where you will actually be treated like a customer and not ignored.
