Missing funds

Hello Its the 3rd time today that i deposit funds from my bank into the ithuba national lottery accout but it does not reflect. I sent emails to Ozow (a group that the national lottery use to transfere funds) and i phoned the national lottery call centre but they said i must speak to my bank and ask for proof of payment but the bank is telling me that if the payment is done through a 3rd party the bank does not have or proof of payment for that transaction but can only provide a bank statement which the national lottery does not want to accept. I feel that the national lottery is full aware that we can not get the proof of payment from the bank and they doing this to rob people. Please help me, i deposited funds in march (R75) in may (R900) and (R50) today 18 july 2019.
