Be careful when dealing with Mondo

Unfortunately I don't remember the name of the agent from Mondo who first phoned me offering me the MTN contract for R399 per month, however I was told that I would only be debited at the end of November, which I thought was great because I am with Rain, and after cancelling, I would still need to pay them end of October. I have been waiting for 1st November to plug my router in and activate the sim card. I received an email this morning from MTN billing saying that my account would be debited R476.23. I phoned Mondo regarding the issue, and the agent I spoke to basically threw hands up and said it is what it is, sorry you were given incorrect information. I am not a happy camper, and am going to struggle financially now having to pay Rain, as well as MTN for A SERVICE I HAVEN'T EVEN USED YET!!! This better be the last hiccup during my 3 year contract, otherwise MTN will lose a long standing and loyal customer and I will make sure to warn every person who will listen against Mondo and MTN.
