Addidas itself is replacing my top that i bouhgt from total sports and they not willing to give me my proof of purchase.

I bought a Real Madrid soccer t-shirt last year November and after 3 months the emblem came out. I know totalsports will not care. so I wrote to Addidas and after a long time they have decided to replace my t-shirt. I called the customer call centre and was told only the branch where I purchased the good can reprint with a transaction no. the lady assisted me with transaction no. 097244. I drove all the way to menlyn branch and they say after 6 months they don't keep any records of purchases and head office must provide it. Customer support is sending me to the branch, the branch is sending me to customer support. Who can assist? does a company providing credit to consumers not have record???????
