KEEP YOUR RECEIPT!
I ate a soup (market veggie) and a pizza (California veggie) on January 3 2017 at 11.30am. If you look at the menu at that location, you'll see that soup costs just over ten and pizza just over twenty. With tax and tip my meal came out close to forty. I'm fine with that - food was hot and tasted great.
What bewildered me when I got home is a charge I found on my card - just over eighty dollars (transaction number 531553336330 5812 from Piz30400154). So I thought it's a mistake, I'll be nice and call them and they'll fix it.
I called the location directly at 7022617317, nobody picked up, left a voicemail, nobody called me back (now it's 2 weeks).
I called the CPK headquarters at 800-91-wecare (92117). No, they don't care - nobody picked up nor returned my voicemail.
Now I called my bank, who said "do you have a receipt? No? Sorry, then you can't dispute this charge."
Lesson of the story: keep your receipts.
