Worst service ever!

My mom and I went to Game Westgate on Sunday afternoon to buy a dining set. Staff members were standing around in the store and when we asked one to help us, he looked at his watch. This is unprofessional! It took him 15 minutes to go look for the set. He came out and pointed in the direction of another person. This guy walked to the front of the store with my mom and disappeared without a trace. I told my mom to go look for a manager while I pulled a heavy trolley with the set on top to the front of the store to pay. When I got to the till, they helped the woman in front of me but when it was my turn, they decided to cash up and hand over to another person. All the while the manager was of no help, telling my mom he saw us on the cameras and we weren't waiting that long. Not one of the staff wear name tags so I can't report their names. But one thing is for sure: They have no problem in taking your cash.
