Clicks Gateway lack of customer service.

Yesterday i went to clicks Gateway and entered the store at quarter to seven. I proceeded to the section where the electric shavers are kept and passed two store assistance having a private chat. I waited at the unit where the shavers were kept for ten minutes before an assistant who was assisting another customer went by and i had to call for assistance. I do understand that it was the end of the day and that staff are excited to end the day of work however whilst standing and waiting for assistance staff members were screaming accros the store that they are zuma's boss 'Gupta' whilst there are customers present in the store. When i did receive assistance i had shown the individual the shaver which i want and he went to the back to get the keys to open the unit. He came back stating that he cannot find the keys. I called to speak to the manager of which Grace Smohela came to me, I had informed her that i would like to purchase the shaver and that the staff member had gone to the back to get the keys but returned empty handed, She had informed me that one of the staff members had taken the keys home when they finished their shift. There are two security officers at the entrance of the store, How can staff take business property out of the store?I asked the manager what do i do now, She rep**** that she can do nothing and that i must come tomorrow morning i i want to buy the shaver. I had explained to her that i am unable to come the following day due to the fact that start work at 8 and that the store opens at 9. The service that i received was very bad especially from a large retailer such as Clicks. Staff needs to know how to carry out themselves out in a professional manor at all times. Such an experience will prohibit me and my family from purchasing from clicks in the future .
