Saravana Stores — customer not treated well

I have purchased in chrompet saravan on2nd april for rs.600 in cosmetic department 5th floor... And by mistake i had a key chain which i bought in the same shop on 6th floor but at the month of march... The ladies who checks the purse said that i stole the keychain and the rate of it was 20 rs i not sure why those ppl can't understand if i brought things for 600 i can even pay 20 nothing is there... But both lady shouted at me as i did some wrong thing... Okay i accept its fault some what from my side too but there is no respect for customer... And today i went there and stated the situation and asked them to verify that i can fetch the old bill but they are saying it can not be done... If once bar code is readed again how the same one is being taken i totally don't understand... I just wrote a feedback in note which they gave me... But i don't feel it may work... So frnds take care o[censored]r respect before entering chrompet saravana... As we will not get it... And from today am not going to purchase anything from there even will not suggest this shop to anyone
