Discovery bank System Glitch Causes me to lose money

I was paying a company for an item on a Saturday morning. I dod an immediate payment and the payment was unsuccessful. I re-did the payment another 2 times and both were unsuccessful. That afternoon all 3 payments went through. I requested that the beneficiary refund my 2 extra payments and give me the item i was to purchase. But i was told that this looks like ***** to him and that he will wait until a month so that i cant reverse the transactions after he refunded me. I cancelled the purchase and requested that Discovery Bank to reverse all the payments. Bear in mind that this is Discovery bank who caused this problem with their system that gave issues. Its been 3 weeks now and everytime i call i get told that they will call me but it is with their payments department. After 11 calls no one has called me and my transactions are still not reversed. I will not recommend switching to Discovery bank. Full of promises and no one delivers on them. Its pathetic. I am in the proses of switching back to FNB.
