Pending deposit

I transferred funds from my Standard bank account to my trading account on the 5th of this month. Funds left my account, however, they are still not reflecting on the trading account. I contacted the company and was advised that they need transaction ID to trace the funds, I wrote to SBSA and Carmen Mbangeni said I need to download a proof of payment which will show this transaction. I checked on my online account for all transactions and could not find this one that was done on the 5th even though funds were deducted. I wrote back several times advising that I cannot see this fund and received no response from her/him. Please help and I will appreciate written response because I do not have access to my phone in the moment.
