They don't want to pay my money back!

I have taken a contract phone in April at Brooklyn Store in Pretoria, and upon making a payment for contract initiation fee of R 250.00, the first speed point was bit slow thus the consultant used the second speed point, so at the end of the transactions both speed points deducted R 250.00 from my account meaning i doubled paid. The consultant issued a duplicate invoice to me and said i should send my banking details the amount will be reversed. As it stands today i have not received my money, i have contacted the store customer centre to assist and they referred the matter to Brooklyn to assist nothing was done, this was in June. Went to Woodlands Istore to get assistance with the matter recently, the managers there were so sweet and they called Brooklyn store to assist, still nothing has been received after sending countless emails all i get is that the transaction is still under investigation.

Since April they are investigation a duplicate payment of R 250.00, of which i sent proof of double deduction from my account. I'm so ****ed and annoyed at this point as they are making fool of me.

Like it can't be that difficult, so now i have to go to slow claims court for this.

NEVER GO TO BROOKLYN ISTORE, NEVER!!!!BORED.
