i made an arragement with finchoice on the 06-04-2016 for them to load a deibit order for me for my kwick advance account on the 29-04-2016 they responded to my email on the 06-04-2016 stating that debit order will be loaded and the amount due is R1565.25 and i agreed, then yesterday the 14-04-2016 i received a call from ssda advisng that finchoice has handed my account over and i should make an immediate payment of R1600 and sometthing , however as far as i knew finchoice confirmed and agreed to the arragmenet that i made with the on the 06-04-2016 and gave me an amount that will be deibted from my account on the 29-04-2016, i can not understand how can you hand somone over after they made an arragement yet the debit order or the arragment that was made did not go off , this is very upsetting and i woud like to know what finchoice is doing about it, and how are they going to apologize to me for what they have done cause it upsetting to receive a call like that yet you have made arragmenets for when the payment shoud go off and as a financial insituation you guys agreeed to that. i want feedback on email by end of business today and not later, cause no one likes to reply
