Don't bite the hand that feeds you

Taking out a new contract in store was a pleasant experience, however it was soured by an MTN agent today who called to offer insurance, despite me declining it in store. When I asked why I'm being contacted about the same product I declined yesterday, she said it's because no paperwork exists. I signed a waiver in store when I declined the insurance, so paperwork does exist. Don't lie to me and don't put the phone down in my ear again! This is your first and final warning!
