I recently placed an order with Keurig for my K-cups and the exact same thing happened to me as above. The only difference is they actually charged me a second charge.
Although the amount wasn't a large amount it was a legitimate charge. I called them and customer service wasn't able to explain they said they couldn't see where I was charged the additional amount. After numerous calls and holding I finally got to the Corporate office supposedly. They said they would refund my money.
That was on November 11, 2014. I called yesterday and had to be transferred and held for almost 45 minutes for someone to say that the first person initiated the refund but had it in a pending status and he fixed that and the refund went through right then.
Well as of this moment I have not received it. I have purchased quite a bit of coffee from them over the last year and will not purchase anymore.
Reason of review: Poor customer service.
Monetary Loss: $9.
Preferred solution: Full refund.
I didn't like: Them making unauthorized charges.
