Cell phone number changing

ok so i lost my phone by accident and couldnt find it but my account needs that number to change passwords and also the cell phone number already used so can we have a button put in so that we can use a go around so we can input a new cell phone number?

i think i said that clearly enough if i didnt then ask for more information.
