S*#%y service
Early this year I received a call from Mondo offering to upgrade my MTN contracts, which I accepted and my data line was upgraded. A month later I realized that my device could not connect to the network. I called in and enquired about the network issue, I was informed that I was given a for-home service. I informed them that they must cancel that upgrade and revert back to my original package as the for-home service is useless as they never gave me a proper device for this service and it would be pointless for me to have a for-home service as I spend more than 10 hours at work. 

3 months MTN and Mondo haven't done as they have promised, and I found myself paying for services not rendered to me. When I enquired about this I was instructed to submit my 3 months bank statement so that they can process a refund, I did that and up to this day I haven't received my money.

Matters got worse when after MTN and Mondo had finally decided to give me a correct package, they decided to classify it as an early upgrade and I was expected to pay and early upgrade fee. I've never requested an early upgrade fee. For the past 3 months I have been calling Mondo requesting that they rectify this mistake, I  am always told that my was has been escalated to MTN. MTN needs to write off the early upgrade fee as I have never requested it, I called MTN to check if they have received anything from Mondo regarding the cancellation of upgrade fee from my account. I was told that there was no such request on my account. Now my lines a locked because I refuse to pay the upgrade fee.
