Total Unacceptable client Service

I am very disappointed with the service I received from your springs branch at the avenues, I contacted your branch via WhatsApp and asked them what my fee would be to leave my laptop for another month then they came with stories of no you need to pay this, and you need to pay that which was not explained to me the day I signed the contract. The person helping me over the phone was very rude and when I asked for his name (Kyle) and said I will come and see his manager he got attitude with me. I Borrowed money went down to the branch and payed the full amount on my laptop. Then when I walked in to collect my laptop, he was sitting there giving me attitude shaking his head and mumbling stuff in Zulu, unfortunately for him I understand Zulu and heard exactly what he said. I asked to see the manager and she went off on me not even considering that her employee is the wrong one while he was sitting behind her making faces at me. I expect that they both are addressed in a formal meeting and that they receive an warning for poor client service because this is totally unacceptable, I will be doing a follow up on the matter and if nothing has been done, I will take further measures against the store.
