No intrest in assisting

We went to Markham to buy a pair of trousers and a waistcoat, when we had to pay the cashier did not want to assist as this was in my husband's name - I asked if my husband could send a copy of his ID along with a letter stating that I could buy on his name and they said no. I asked if there was a Markham in a different town (as this is where we will be for an event), they said no. I also asked if they could assist us in any way and provide us with a solution, they said no. There was no interest in assisting us from the CP's side. I don't think that this should be the behaviour of personnel in store and they should be there to help and provide solutions. I would like someone to contact me with regards to this as I am upset with the way in which this was handled.
