Well, I got my MissFresh delivery on Sept 3. I don't think I'm getting Miles for it so I will have to file a claim in January lol.
One bag of pizza dough had burst open in transit so I emailed them. They gave me a $20 credit for a future order, and also said they would refund my credit card $45 and give me another credit of $45 as there was a back to school promo code I hadn't used. Weirdest thing is they told me they'd add a $45 credit to my account on Sept 5. It was there Sept 5 but I didn't want to order the next 2 weeks meals so I didn't order one.
On Sept 6 I log in as I changed my mind and thought hey, I'll try it considering they are giving me $45 off again, and the credit was no longer there!
And since others said their 500AM posted quick, I'm pretty sure now that means my miles are not coming!
