Terrible customer experience

Sheet street Clearwater mall store manager has 0 customer service skills and is very rude .. I wanted to return a pencil case that i bought on the 11th Nov, i had the eft slip and not the detailed transaction slip the staff told me they can't assist without the slip which i could understand i asked them to reprint they said they can't they even though they have the slup on their system, i asked tge staff to escalate the matter to the manager, they said they will have to call her cause she is not available, when they called her, she said the same thing that i need the detailed slip when i asked to speak to her directly she blatantly refused and said she will not be speaking to any customer as she is at home and that she told the staff what to do... Practically said she wil not be engaging any further.... This is more of a customer service complaint more than it is a return of item policy complaint... You guys need to train your staff better especially the mangers they are absolutely rude!!!!!!! I will await your feedback in this regard!!!!!!!!!
