I actually tried using the Visa version on a ~$400 Canon wide format printer that died on me within the card warranty.
Holy Schnikes! What an exercise in frustration!
Visa contracts their service out to some third party waste of oxygen, whose entire business model seems to be based upon exhausting their customers into giving up prior to paying out a claim.
I probably spent 10 hours in total trying to get this resolved.
Beyond the fact they initially insisted in conducting all business via snail mail with a big lag time in between transactions, we went round and round for weeks on their insistence that the contract
REQUIRES a repair estimate, as only they have the right to decide whether to repair or replace the unit.
There wasn't a repair service (including Canon) I could find that would provide a repair estimate, as these are apparently disposable consumer printers, and Canon apparently no longer provides replacement parts even if the failure could be diagnosed.
Card services says, "No estimate, no payout."
I finally convinced the local Canon factory service center to write up a service estimate that stated "cost to repair exceeds value of printer."
Still no go, as card services claimed they required a $$ amount on the estimate.
Several more escalations, and card services finally decides send me a replacement check, but when it arrives, it is ~$80 short of my purchase price.
More phone calls, and card services claims they found some third party individual Amazon seller out of Florida who had 1 unit available, unknown working condition, for less than I bought from an authorized Canon store. Not only that, the seller made up the difference with some outrageous shipping price I would have to pay, to which card services says: your tough luck, the contract doesn't cover replacement shipping.
Card service says that their assigned value replacement is not what your receipt states, it is whatever the lowest price (commercial or private) their CS rep can find anywhere on an internet search, less shipping.
A colossal waste of time.
