I have recently (a few months back) upgraded my tv box and modem to the newest available I believe. Anyways I do believe I set up a 4 digit purchase pin way back years ago on the older Shaw box to keep my 35 year old son from ordering movies without permission. But a few weeks ago I wanted to purchase a movie( which I never do ) and up came the screen asking for the 4 digit pin. Needless to say..... and the reason I’m here, is the pin I use for everything didn’t work. 5 try’s and it locked me out. 
Loooong wait time, eventually getting a person to talk to on the phone and going through several different steps at “My Shaw” trying to reset the “purchase pin” by resetting the “parental controls” as instructed, seemed to frustrate the service tech on the phone as much as it did frustrating me. 
Take note: the tv in the bedroom accepted the purchase pin and after stopping the movie in the bedroom I was able to restart the movie in the living room without asking for the purchase pin. 
Please help if anyone can, I am wanting to RESET my purchase pin so I can sit in the living room and purchase a movie. Keep in mind attempting to reset at “My Shaw” website didn’t seem to work as I was instructed.

thanks for any help provide
