No response / service

I purchased a Woolworths electric blanket last year winter. Now its winter and I try to turn it on again and the lights on the control are just flicking - and it wont work.I dont know where I have put the instructions so I phoned the Woolworths customer care line and spoke to someone just to ask him if I could please just have a copy of the instructions book so I could see what is the \troubleshooting"problem so I could rectify this problem. (It says on the back of the control \"" Refer to instructions as to what flicking lights indicate troubleshooting error is\"") He told me this is impossible. I paid a lot of money for my electric blanket. This is the sheepskin queen size fitted blanket. I was not unreasonable and demanding of a new blanket or anything of such sort - which I think I could have been since I have used it barely for 3 months of winter last year. Why wont they help me? I really dont have another R1000 to purchase a new one. I shop at Woolworths every month for my groceries and I feel so disappointed in their attitude and service that I have received."""
