CELLPHONE ATTACHMENT

I bought an ARB HAUWEI Y530 cellphone from Markham in May, 2015, It had a selfie stick with it, which was not functioning at all. I went to the shop to request if they could show me how to operate it. The lady there showed me how to time the shoots. When I told her what I need to know it to use the stick, she was agitated and she told me that all the selfie sticks they supp**** with these phones are not functioning, so she does not how to help me with that problem. I asked her what does she mean? Her response was that as the phone is alright why should I bother about the Selfie Tick. At this point I ask her what did she do with the others? She said nothing. On that note I requested that I would like to turn in the item for FAULT her response was that she cannot do so as the Selfie Stick was for free, so why bother. She even went to ask me where would she send the ITEM to?In brief, I booked to item and the cellphone anyway on 01-07-2015. Hearing nothing from then on 04-08 I went to find out. I was told that they have not had anything from MTN. I request to reverse the sales that was refused up to this date. Should I suffer without a phone for 2 months?What kind of service is this?
