Voucher money transfer withdrawn from pta Absa pta

Good day I went to ackermans store church street in Pretoria to do money transfer on the 10th of june the lady by the name Pontsho Radebe assisted but she failed to explain that they don't transfer over R4500 at once we have to devide the money into 3 i didn't have problem with that.1 gave her R15010 first she processed but the printer went off and the receipt didn't have the voucher number she then contacted their customer service to retrieve the number and forwaded to my phone. I then give her another R15010 she processed and give me the receipt. When i gave her another 15010 she said i have already reached the limit for the day coz i have used 1 ID twice so i can't send the other R1500 .i told her that you should have told me from the beginning coz now i wanted to send this money once off to my mom in Venda she is waiting for the money.Meanwhile i was still in the shop i called my mother not to go to town as the money I've send it's not complete she will go tomorrow after i have send another one. Pontsho and Barbrah apologised for the in convenience. I then leave the store. Yesterday the 11th my mom went to Absa Atm to collect the money as i was already given her 2 vouchers she contacted me saying the voucher i gave her it's not working i said maybe you miss the number let me give the number again, but she kept on saying the number its not working. I contacted Ackermans customer service and speak to Jenino and Themba gave them ID Number to check what's went wrong. They said the voucher was withdrawn on the 10th 13:47 from Absa Andries Street Pretoria. Which is not 5min from the store. I asked them how did the money withdrawn while i have the voucher and the pin with me. they said they dont know i must go and open the case from the police station. As I'm saying the case is opened against the store and Ponstsho still waiting for case number to be sent. I'm really frustrated at the momemt coz my mom she had to borrow the money from other people to go back home hence didn't have the money. Please help i dont know what to do that was my last money a d my mom and the kidz are starving . I really want justice to take over i want my money
