Bad client service

I ordered a jacket online then I received it then it was small, i went to Exact in Knysna to return it yhooo😭😭😭😭 i went there to ask first what r they gonna need and the consultant said i need the slip or invoice then i went straight to my work place to take the item when i check the packet i saw that the is no slip then i called online to find out what must i do now then the lady told that they emailed the invoice then i asked her if i should print the invoice and she no i dont need to print they can call them then they will email the to the store then i went to the stores with high hopes thinking that everything is going to be ok... Guess what 😢😢😢💔💔💔 i explained everything to the consultant and she said i must email the invoice i said i dont have that and she called so called manager she didn't ask me anything she said Sis u r trying to be difficult and im not going to allow that with my stuff as we can not assist you without a slip then it is your choice to email the invoice or you dont and dont make your problem my problem.I tried to explan to her and she said maam i going to say this again '' im not going to be able to assist you without invoice email it to the branch or not it is up to you '' she shouted at me in front of the customers then i came back with the item feeling so disappointed and embarrassed.Then i called online to find out what must i do now with the item as i wont go back the manager of Exact again. I was assisted by Phelo from online customer care then she said she email the invoices to the branch but that was to late because i was not interested so told her how i feel and im thinking of closing my account of rather go to George to spend my money when i gwt good service...
