Return of damaged flip flops

On the 16th of September I bought flip flops at Totalsports within a month already torn I went to return them I found a cashier lady who was friendly so for confirming that I returned the flops she called the store manager unfortunately the phone was on loud speaker she was angry telling her customers are so tiring I then answer her that all I need is quality flops then she demanded video call which I refused as I think it was violating my consumer rights.
