So for it to not be associated with me I should give other adress not my home?

No need for a change of address.

A fake signature simply means you're (seemingly) not the person who signed, regardless of where the event took place.

Also that I got your atention I would just like to know the success rate of the method wich you replace a expensive item for a cheaper one and claim it was their error? Specifically for clothes, for example nike, tommy hilfiger, carhartt, etc... I would just buy a expensive item and then replace it for some cheaper t-shirts that would match the weight. Is it possible and what are the details I should care about when doing this?

It's called the "wrong Item received method".

For an In depth understanding, refer to the articles on my blog.
