Not good customer service

Yesterday 14/05/2015 me and my mom went to Samsung Clearwater to return the Samsung Curve which costed R14999.99, which was purchased on the 07/05/2015 . When we got to the store, the consultants on the floor were assisting in a good manner till things changed when we got to the manager of the store, Karishma. The Manager does not have good customer service, she was busy on the phone seeing us we were there to be assisted,. She kept on answering her phone rather than delegating someone to take her calls while she assists us. She eventually told us that the tv has elapsed the 7 days notice in order to be returned as yesterday was the 8th day, She said the 7 days notice starts on the day of purchased, which she is lying. The manner that she was assisting us showed she didn't care about us. We were at the store for more than an hour for something that would have taken less than 30 minutes. She does not have good customer service, SAMSUNG PLEASE EDUCATE YOUR EMPLOYEES HOW TO TREAT CUSTOMERS. I WILL NOT DO ANY BUSINESS WITH THE STORE DUE TO SUCH BAD TREATMENT WE GOT.
