Gross Negligence

Hi I would like to report how disappointed I am with the service I received from Exact Store at Traderoute mall. On the 8th of June I went to buy a phone,model and model of the phone is a Hisense, it's a dual Sim phone. The cashier that assisted told me that the store does not have any Sim cards, she requested that I give her my Sim card so that she can put it inside the new phone. So I gave her the phone so that she take out the Sim card. When she was done I took the phone and I went back home thinking that my Sim card is inserted,to my surprise I was not getting any calls or smss I asked my family members to try calling me but it would just ring to voicemail I decided to send a please call me to one of them. That is when we discovered that this was not my Sim card and this was 3 days later. I went back to the shop to find out what did the cashier do with my Sim card, I was told that she is not at work as her child is sick. I spoke to to the manager who told promised to call me back when the cashier returns to work.The manager also told me that I will have to go to MTN and the police station to get an affidavit so that they can be able to do a Sim swap for me. I told them that I do not have money to go to the police station and they should do that for me as it's not my fault .The name of the cashier that assisted is Michell. I am still waiting for a call from them.
