Unfriendly and unprofessional service

I'm totally shocked at the service from the totalsports at the phoenix plaza. I bough a pair of Puma on the 24/12/2021 using my card. Somewhere in June I realized the shoe has been getting cracks. So on my first on day, i took the shoes to the store. AT the store , I has to ask for the manger as no-one bothered to assist, I was assisted by one of the staff who informed that the manager was 'out'. and he will take a pic of the shoe and get the manger to call me in 48 hours. He then asked me when I bought the shoe which I gave him the date ad his reply was 'there is no returns' after 30days. I then waited for a call from the manager and 10 days later , there was still no reply. i then sent an email to totalsports after 11 days of waiting and 2 days later I got a call from the same staff member. to every question that he asked , I gave the answer and he kept asking more questions just till he could get to the point that that they wouldn't refund or exchange for me. I find it strange that 1st- he speaks to the manger on loud speaker and relays the message to me. Why couldn't the manager just speak o me himself as that is his job description. Secondly- I was first asked for the receipt, I said I have the bank statement as proof of payment, The staff apparently said that I could only use the original pop. I then was asked for the box of the shoe as I only brought the shoe, I did reply that I have it at home. I then was was asked for the date of purchase which I gave him, they they rep**** that he cant help me as its 7 days pass the '6 months' warrantee which originally he said was one month. So must I buy a pair of shoes every 6 month ( bearing in mind that I only can use takkies on weekends)? Does the staff even know the policies and procedures of the store? So does the manager not directly help customers with their queries?
