very bad attitude

On the 20th October i went to Jet store in alberton city to buy a cellphone. I was served by one of the consulants. she tried to switch the phone on several times but it did not switch on. she put it in a charger and it still did not switch on. it was a concern to me because i normally buy cellphones and they switch on immediately. i asked her if she can give me another phone and she said i must speak to Candice Jansen because she is the one who says i must wait for 10 minutes before the phone can switch on. i went to speak to Candice that i am not comfortable in taking the cellphone as it is not switching on and can't they give me another one, she started raising the voice at me telling me that i have to wait they are trying. while we were busy talking the consultant came and showed me that the phone is switching on. I told Candice that should the phone give me problems i am gonna bring it back, she rep**** by saying ARGHA. which is an insult in our language. i cannot allow her to insult me like that if she can't give customer service to people she must go find the job somewhere where she wont be dealing with customers.
