DSTV *****ULANT TRANSACYION

I am long yime clients of dstv. I have a debit order that deducts the monthly payment. In October the drbit order did not go through. It was a Sunday that i recieved a msg whicj stated that my payment did not go through, and that i must click on the link to pay. I did so. On this link however was only amount of R3700. My dstv payment is R1850. Since this was on a sunday night i paid that smount, because i was scared that the service could be discontinued. Now i cannot get my money from dstv. I went into their office in our town. Send them my id. Bankstatements etc. But to no avail. I cannot get my money from them. They stole my money!!!!
