Worse customer service

We purchased a phone for our 5 year old son in starwood ackermans 2 day ago. We did say it was for tik tok and games however this phone does not support it. We came in yesterday explained that we wanted the phone for these apps and we were told that the manager was not in and we shud come in today. We decided to go to another ackermans and were told that they could assist by calling the store because we were mis informed and we shud get help.we came in today and sat here from 9 the staff dont seem to care we spoke to the manager who took so long to come in as she was busy doing her personal shopping in spar. Why wud one store authorize an exchange and this store reject.. they are too busy on their phones and personal things to care about customers
