Capitec Sucks

I have a personal loan with Capitec, when took out the loan I told the consultant that I don't have a fixed date for my salary and that the date has to be on the last day of the Mont. To date they try keep deducting on the 27th after I have told them I don't have a fixed date. Now I have had the last of my money taken out of my account and I haven't been paid yet leaving with me no money whatsoever to get to work or buy food. I called and the funds was reversed and then a few hours later it was transferred out by Capitec again. What must I do I can't fone them they kept me on hold for 20mins the first time.
