Was in my local gym trying to set up a membership and someone was in there screaming that it’d be easier to “burn the gym to fucking ashes” than cancel the sub. Turns out the cancellations person was only there on a Tuesday at 10AM or something useless.
Just tell them you moved, that's why you're canceling, and you live nowhere near any of their other branches therefore it would be physically impossible for you to come in.
This works for me, and I have no qualms lying to circumvent stupid tactics like these. I have turned into a LIAR when speaking to customer service for stuff like this because it just makes me more sympathetic as a customer, even though it's insane and unfair that one has to do this as a sort of social hack instead of the business just doing the right thing.
Worth noting that in the UK if you say « this is obviously predatory and isn’t going to hold up in small claims court » this requirement almost always disappears and they tell you that just this one time they’ll be nice and cancel from today.
