Eureka Forbes — Irresponsible customer service

I purchased a EUROCLEAN wet & dry vacuum cleaner on 30/12/2013 from ALUVA ERNAKULAM office. Its been a very bad experience which we received from eureka, that on the first use of this machine for 10 minutes the PVC flexible pipe got burned and suddenly got separated from the socket. We got shocked and immediately contacted the customer service. past 02weeks these customer people are fooling us, and there is no such action from eureka Forbes side for the replacement of this machine. At the time of delivery and demonstration these sales team were extra pushy and smart enough to fix these faulty material to customers,
Respected higher authorities should really focus on the customer service side as well the particular product mechanism. Please advice us what all procedures should we complete in order for reimbursement formalities as per the EUREKA FORBES refund policy .(30 days money back guarantee).
