BAD SERVICE - NOT THE FIRST TIME

I was looking for a particular Melissa and Doug item at the store. I googled a picture of the item on my phone and showed it to the staff. I requested for them to check for it on the system to see if it was in stock as I could not find it on the shelf. I was first told that the store did not sell the item. The manager agreed to this. When I told the staff I purchased the item a week ago from the store they asked me if I was certain and did not believe me. They refused to check for it on the system and proceeded to then say if they did sell it, it was sold out because it was not in the stock room. Ready to leave the store without the item, I described the item to another floor staff member and a customer overheard me, the customer then proceeded to pull the item of the shelf and hand it to me. The item was not in the correct place as I suspected, and there was more than one in stock. At the check out the lady did not apologize after seeing that the store did in fact sell the item and that it was in stock. I am very unimpressed by the level of service at the store and this is not the first time I am experiencing such poor attitude from the staff at the V&A Waterfront store.
