I just had the exactly the same experience with wag jag On a window cleaning service -
Expired before using. My fault. I requested a refund for the purchase price
Wag jag reluctantly put a credit For the purchase price on my wag jag account citing
A one time goodwill gesture. Like they were doing me a favour. There is in such guarantee on their website
I think we are getting confused with wag jag and groupon
Groupon is the one that says it never expires -not wag jag
