Repayment of my credit balance

My DSTV account must be paid within 24 hours of due date or they cut off my services.<br> 2 weeks before the end of December 2015 I phoned in to DSTV South Africa and stopped my services and checked while on the phone that they did it, was done. I also asked \would there be any further charges at the end of the month or thereafter""; however; when asking how long before it would be paid into my bank they rep**** 40 or more working days.<br> I must pay them within 24 hours or; but I must wait 40 or more working days; this is wrong; unacceptable and ludicrous;it's my money and then they still pocket the interest for the time """
