Ithuba Lotto *****ing Credit

I have bought on the 14th October a R250 1voucher to recharge my ithuba lotto wallet on my app so when i recharged the voucher the app gave a error message so i put it in again then the app said the voucher has been used but it is not reflecting on my acc. So i contacted flash where i got the voucher from and they told me it has been used on the lotto app and i should contact ithuba. So i have sent them an email on the 16th October and told them what happened. They said that the credit department will look and come back to me. Today is the 7th November and i'm still waiting for my credit to show. This people are *****ing our money with they errors on the system.
