Mobile Money Service Transfer

went to Pick n Pay Montana Hyper, contact details, *** shop HC17 to send money to my brother on sunday after of the 03 May 2015. on the 04th on a Monday my brother went to Pick N Pay Arcadia sterland in town to withdraw the money then he was told the service is not working and he must come back again. It was around 13:00pm when he went to Pick N Pay, he went back again and they called mobile money service customer care number at *** but still they couldn't help him. As am the person who sent the money, I went back to Pin N Pay Montana Hyper to check what is wrong with the network at 18:00pm only to find out I also cannot access the service but Vodacom people could transfer and withdraw. They called mobile money service again and they couldn't assist and told me they don't when it will be working and I must keep on trying. I asked them to reverse the transaction and give me my money back and they told me I can only get the money in 7 days. This money was for my brother to go the Doctor and I used the service because I thought it is a convenient/fast/easy service one should use but it turned to be my most nightmare. I feel they have the money and now blocked him
