Disappointing and rude staff members

I received a call from telkom centurion,on the 10th February 2022,to collect my cellphone,that was ordered and ready for collection On arrival,I met with Sibu who,instructed me,that the phone was ready for collection,however the free gift was not available at the moment and that I should return the following week. I,then returned today(17th February), only to find out, Sibu is no longer working there,nor did she leave my "gift". The floor manager was so rude,refused to help in anyway,she called Sibu and says I should have been there yesterday and now they cant helo me,but noone called me to inform me. They also refused to let me speak to her.
