MONDO for MTN worst service received

I bought two data Sim and was advised by the call center agent that I can Sim swap my number to the new Sim both for me and my daughter. You can't use a data Sim to receive calls and for almost two months I don't get sms or calls. And even now Im waiting for them to cancel the two contracts so I can have my number back. They can give you time line and when you call again say you were assisted by a new person who doesn't know the correct time lines to resolve queries. I was given false info by the first agent who sold me the Sim cards does this mean the entire Mondo staff is new and unknowlegeable

I'm so disappointed at Mtn for using an *********** company for their contract.

Since I don't get calls on my cell anyone who is competent can call me on my relatives cell numbers *** ***
