Poor Service TymeBank

I went to Pick n Pay at Westwood Mall today to make a deposit for my Grandpa I was advised that they dont use account number but they use the code that you generate from the app so I then deposited onto my account so that I can transfer to him. I deposited R2000 at 10: 07am up to now it has not reflected. I have been trying to contact TymeBank Customer service ***and I am not getting any assistance.
