I bought a batch of parts from DigiKey mid May, including a cut tape of 100 items that cost £200+. They arrived in a couple of days as normal, packed everything up and sent them to my assembler. Roll round to mid June, assembler doing a check before loading their machine says it's the wrong part in the DigiKey bag. A few photo's later and sure enough, the tiny ICs in the tape are 5 pin and right ones are 6 pin. The labels on the bag are correct, just the wrong item packed. They only come in the one footprint, so I know I hadn't ordered the wrong part in error (been there, done that).
So, a month after delivery, I give DigiKey a phone to ask what the options are. About 6 minutes later I had an apology, a refund on my card, and no need to ship anything back. I was quite impressed really. Still waiting for the odd part to come back from the assembler, as I'd like to know what I know have 100 of.
