[Resolved]  Eureka Forbes — Refund issue

Address:	500028
Website:	Eurekaforbes

I have bought dr. Aquaguard on 17th june. I received the product on 21st june. The service person came on 22nd to install the purifier and found to be defective. On 23rd  eurekaforbes technicians came and found to be completely defective. I have raised refund on 23rd.
Sales person convised us to go for replacement, instead of refund, for which i aggreed. But from then i have not receive any response either from eurekaforbes nor sales person. I have dropped many emails, called cust care... But in vain. They havnt collected the product also.
So vexed with the situation i have again raised for refund, but now they said due to gst 18% will be deducted. I bought this product before gst and paid including all taxes. How gst applicable now? This is such bad experience.
None give proper response. Plz do look into this issue.
