Unhappy customer from mams mall truworths

i bought shoes at truworths mams mall it was july 02 , October the shoes are torn/ damaged before they can reached 6months which is according to their policy they should be able to last that months. I reached out to the store and the manager whom i spoke with said since i don't have a slip and i bought the shoes cash i should bring bank statement that shows the transaction they will be able to trace it since it will show the date . i did that when i arrive at the store the manager who was on duty at the time said she can't help me i should wait for the manager whom i spoke to to come and help me. She further said that she was going to help me if i was an account holder. So basically they do not care about non- account holders. So if the two store manager from the same store are saying two different things.which one must trust. When i inquire from the other branches they told me that the store should trace the transaction from that day so that they will find the transaction number and return them to the store as damage. So the are taking me from pillar to post. I disappointed with their service and how they treat non-account holders. So i have to accept that truworths now is selling us ****S.I cannot accept this.
