Bad service at golden walk ackermans

I went to Ackerman today to check my phone that I returned which was faulty.. I waited an hour to get feedback if my phone was fixed or not, I even informed them that I'm still rushing somewhere can they please assist me, the staff kept going up and down with no one coming to me and giving me feedback as to what is happening with the phone. I ended up leaving the store with no communication nor feedback regarding a purchase I made with them. I'm asking myself why am I not getting the same service I did when I came to purchase the phone, I'm not even sure if they attended to the matter or my phone went missing
