Battle to get my money back!!

Worst Service Ever! My account got debited with additional amount, Due to an error on their side. I have reported it to the Call Centre and on Facebook. Their response is always: "its been escalated and will be attended to". This is unacceptable that i have to wait days to get MY MONEY back. I have a 2 year old son and depend on that money to provide for him. I wish i could speak to someone higher up in the company, but seems like they don`t care about their customers.
