Money still not credited back into my account!

I was told by Mondo that my query has been resolved and my money will be credited back into my account on the same day it was debited which was the last day of the month. However, the money is not in yet and it is now six days into a new month. How long should I follow this up while I waste my resources in the process, this is not on. Sending emails, posting these reviews and making phone calls is not free and I have wasted a lot of money trying to get to the bottom of this, I am now really ****ed of by this. I WANT MY MONEY and I will not stop until its paid back. What is causing the delay now, why is my money still not paid??? Christine, what is going on!?
