*********** and disrespectful managers

I send my son to the truworths mall of the south to exchange a shirt my wife bought the previous day(shirt had stain on it) we obviously did not see the condition of it until we got home as we were the last customers in the fourways store on Sunday at 16:00 after the store closed and did not want to keep the staff any longer. I live 5 min away from mall of the south and assumed that i could just exchange the shirt at the branch....but to my shock the floor manager told my son to go and exchange it in the store you bought it from. Like i said i live in the south 5 min away from mall of the south and where i do my monthly shopping including spending a few thousand at truworths and the only reason we bought from fourways was because we were visiting family in the area. it was not so much what she said but how she said it...*********, no customer service at all i honestly dont know how in the hell she got the position and this is suppose to be the face of truworths WOW. she made it look like we wore the shirt and now trying to bring it back...i was never this disgusted by anyone and to top it off the manager was not any better so it was clear where the floor manager got her training from. my wife has been begging me to open her an account but as i dont like buying on credit but need to have credit profile so was considering it but after all that truworths just lost a huge fan and customer for life because of *********** managers. Im typing this 5 hours later and still feel sick to my core. still cant believe what happened and this after i just spend so much money. I will definitely not return to the to purchase anything in the future, what i will do is go in just to see if the two *********** and disrespectful managers are still there and if the service has change that i will do
