I recently received my Star Sister 3 pack, I was underwhelmed to say the least. But I got a nice surprise in that they only charged me $31, now yesterday I got a second charge for $43. I understand that the figures are up for $66 on Matty.com, but is it legal to charge someone a second time when they already have the item in hand and paid for? I tried talking to there customer support in -surprise- India and got nowhere. I just believe that if you make a mistake, you should swallow the pill, and not charge someone for a second time after they have received and paid for the item.
Seriously is it legal to charge someone more, after you have invoiced them one amount and delivered the item?
