Unprofessional service

I went to edgars in la lucia on the 25/07/2018, I had purchased items and wanted to pay my account. There was only 2 cashiers. The one was busy with customer and other one was trainee. Trainee clearly didn’t know what she doing and there was no one there to assist her especially being a month end week . She didn’t know how to cash my items , how to view my installment and provide me with a gift receipt. She told me I had no installment due however I paid r500 , when I reviewed my statement I do have an installment due in which I have now short paid . When I left the store I was stopped by security at clicks as my packets was beeping. The bag I purchased at edgars the cashier didn’t remove the security tags. The service was unprofessional and embrassing for me
