I sent materials for rebate several weeks ago but I didn`t receive amex card yet. but my friend who sent materials in same envelope, get the amex card last week. So I called customer service and sent everting again and find out the rebate is processed under my friend`s name. If my friend got money instead of me, it is totally okay for me. But my friend only got $100 of Amex card once but the total should be $200 if she gets mine. (we live in same building and when she checked her mailbox, I was next to her.) To prevent these mistake I used stapler for both of our documents but they made mistake and they don`t even know where is the rest of $100 gone. Of course, they denied reprocess the rebate. I asked them to send me any type of record by email, but they didn't send me back anything. And the customer service said, my friend should call them to find out where is $100. We will call canon customer service at Tuesday, and find out what happened to rebate but I`m pretty sure they are lying to me to cover their mistake. I`m so disappointed to Canon and never buy Canon again. If they can`t prove they send $200 to my friend, and keep lying to me I will sue them. If anyone has similar experiences please let me know.
