i've worked at a call center years ago on the retentions dep. of some mobile internet provider. after learning of such trickery, i'll fucking tell everyone that will listen "hey mate, you've got a internet/telephone/cable tv subscription? are you in the "fidelity" period? (yeah that shit is a thing here...) ok so listen, AS SOON AS a second passes from the end of the period, this is how you get the actual decent price for service..."

some people had to stop me on my track several times because i was repeating myself to them (forgot who i'd already told about it) because i must make sure everyone knows

been doing it all these years
