Reliance Digital — Extended warranty

I purchased a 55inches lg tv from reliance digital and with that their sales person had convinced me to extend my waranty for 3yrs under Reliance for 21000/= they told us that any prob shall be solved by them within 4-5 working days. now my tv isn’t working for 4 days, and the repaing bill is 5000/= n waiting period given by reliance is 15 days-1 month. I m totally dissatisfied with their sevice, with such a small amount of repairing bill if they say 15 days what would have happend if the bill was high.they are continuously saying parts are not available but i enquired lg service center they told me they shall repair it within 6 days. I simply want my money back from relince, and I WILLNOT RECOMMEND RELINCE EXTENDED WARRANTY TO ANYBODY, if i could i would have given -5 stars for their after sale service.
