Bad service

I have done a loan and was approved and i also accepted a Debicheck from my app..to my surprise money was not credited on my account..i phoned them the consultant said i must refer to my bank..went to my bank the Debicheck is showing on our side..i called again they said it expired i must wait for them to send another one..a day later called again they said the mandate is sent just waiting for my approval ..went to the ATm nothing is showing..equired again at my bank they stil cant help i have been refered to Capfin..i use capfin because is easy n convenient but now im so dissapointed with the service im getting..from the 20 Jan til to date still dealing with this..im not happy at all...im a customers in between consultant that cant solution me.
