Mondo real ****s

I have signed up a contract with Mondo-Telkom deal beginning of June. they debited my account, sent me a message to say my order is on its way. I called Mondo on the 26th June to followup on my order. They said there was an error on the delivery address, they have fixed it my order is on its way. Today the 3rd, I called again after seeing that its been more than a week without any communication from Mondo. Their consultant told me that the postal code is wrong, again. when I ask them how so because I called last week it was the same story even now. what kind of systems and people are you using who cannot pickup the postal address? they don't even bother to notify you as a client that the postal address is wrong. this are real ****s, and when I ask my money back they are refusing. do not buy from this people they are real ****s.
