Poor Customer Service/No Service

In the past 2 Weeks I have been to two TFG Group Stores, One which I have made a purchase from which I received no assistant from anyone in the store. Yesterday, I have been to Markhams at Gateway to purchase a suit that I have been looking for, after finding it to be exactly what I want. Going to the store to purchase it and received no assistance from anyone at the store, it was as if I was not in the store at all. There was no size available on the coat and with nobody to assist me. I had to then proceed to the cashier to ask for assistance with the size and was advised that they do not have the size I request and non of the other Markham stores has it. Then the guy says to me that size 107 on the Coat is the largest in Slim Fit Suits. After being really annoyed and irritated with the advice given to me. I found other slim fit suits with a size coat ranging up to 117. I use to like shopping at TFG Group Stores and now with strike 2, I dont want to have a third experience.
