Apalling service at Mall at Reds

I went to Mall @Reds to resolve my sons account on his Mega4U account. His account is not linked to my account. I went about 2 weeks ago to get his account linked. The lady wanted to rush me and told me to come back with my son for his fingerprints. The manager also said the same. I asked what they required they told me they needed only his birth certificate, my id and my son who is 16. I took him today, in my hand I had a utility bill. the lady just looked at the utility bill and said I cant help you the utility bill is old. I told her my son is already Rica'd she said than what do I need, I explained to link him to his app, she than said where is his phone, I said I didn't bring it, she said sorry I cant help you, I said you can use my phone, I asked her what was her rush to get rid of me as I am a client and require her to service me, She than said where is Mega4 u card, I said I forgot it , so she said oh you see we cant help you. I told her that the other lady told me that I needed to bring this. The manager also came out, I asked her if she remembers me, they gave eyes to each other and said oh she doesn't have the card, we cant help you. The service I received is appalling. She even did the same thing to the lady before me. I think someone should please look at the service in this branch. I had a similar problem at the Teller. I took my helper and they put in the wrong id number and told me we had the wrong id, the teller went to the back and came back after that she started helping me. Is this the service we are getting. If this continues, I will close all my accounts and move them to another bank as this is really a big problem.
