Horrible customer service

My colleague and I arrived at their store about 30 minutes before closing time and some management and their staff members told us while we’re inside that they want to go because it’s nearing closing time so we told them we won’t be long and we just want a few items, not even 10 minutes later we had staff members telling us that they want to go home and we should hurry up or nobody is going to assist us at the tills, we arrive at the tills and literally staff members were leaving and going home and switching off the lights while we were still inside, it was disgusting the way we were treated as customers
