2 Stage Verfication is useless

My old tablet died and I bought a new Samsung Galaxy Tab 9+ 5g from their reseller. During the setup process I was asked for my samsung account. I only had my login but no password and I could not remember my old phone number and my old tablet was broken but their 2 stage verification insists on sending their codes to this old number or broken tablet. After many email exchanges they say understand my concern, but refuse to help. All I need is for Samsung to remove the 2 stage verification on my account and allow me to reset my password but this they cannot do. They prefer to choose their product over their customer. Suffice to say I will never buy any Samsung product again.
