Bad service

I purchased a top loader machine last year 21 March 2016,which I haven't used..now recently I use it and the tumble dryer doesn't work.I went to game Pritchard on the 5 September 2017 and nobuntu the admin lady told me there's no record of my purchase, then was referred to Mafika nhlapo the appliance manager he didn't even show interest in my matter, he was busy answering his phone telling me there's nothing he can do as there's no record, how come the big store like game doesn't keep records they need to fix my machine now they come up with excuses.. I bought this machine cash.. All I need a the slip ..copy of proof of purchase.
