Gyftr.com — A voucher which can't be used in any case (Healthian Voucher)

I bought few heathian vouchers worth 1500 from there website since it was saving me around 12% of the money. But the thing is when I use the voucher on the healthian website, it remove the discount that is available on the healthian website which means if I use the voucher, I will be paying more as compared to when I am not using the voucher.

I waited six month to see if there is any way I can use this voucher on the healthian website. But All the healthian products come with a 30% discount and that discount is not available in case you use the voucher.

So basically I lost my 1500 rs by purchasing the Healthian Voucher from GYFTR.

Here is why I think this is a fraud: Since their is no benefit o[censored]sing the voucher why this voucher exist on the GYFTR platform.

I explained the same to the customer care but they doesn't seem to care
