Unprofessional and inefficient service!

I made a deposit for my brother's small public phone business on 23 March 2015 at 9:05 am, so that One Cell can credit his account with airtime. I filled in the reference number and all other information correctly. The teller must have neglected to insert the reference number on the computer, so the deposited amount does not reflect on the One Cell account. This is the first time such a thing happens, as I usually transfer money from my FNB account and always use the reference for immediate allocation of funds. This has caused my brother close to R700 loss in revenue! I called ***, where I was told that they are not allowed to give out branch contact numbers, and I will have to visit the branch. This means I will have to take time off my work, drive to Tsakane to get the problem solved! I have a copy of the deposit slip, one would think with so much technology available in the country, I would just be able to send them a copy of the slip!
