1-) Take a look on the original email, if its
example : naughtylee@hotmail.com
create a gmail called naughtylee@gmail.com .

2-)Just say "? cant access my old email" nothing much nothing less we dont wanna fill our support with unnecessary things,

3-)Fill in the login name,sum name,region,
On the date of birth- Type " i dont use my real info on any website for my security including my dob." or similar stuff like that,

4-)Now the country, look at the original hotmail if it says hotmail.fr you know its france, if it says wp.pl you know its poland etc.

5-)You can type who had access part only me or if u think someone logged in you can just use my big brother card, since its someone in your "family" it wont be a problem.

6-)Do you remember store information? = Say yes to that and follow
Go to lol client, then collections, then the date acquired put the oldest skin as a first ever rp purchase with item and date.

7-)Now check the accounts refund rights, if it has couple just use them and refund a champion on your like, then type those in the "what did you use your tokens on?" part.

8-)Now here comes the a little tricky and hard part, first 5 champ bought, lets say the oldest skins are belongs to master fiddle akali try and riven, i put them as a first 5 champ purchased

9-)Oh i forgot the account creation date, just roll the oldest skin couple weeks back. and put the date u got.

The reason why this method isnt always working is because of the first 5 champ is a little gamble,

From my experiences if you encounter Riot Skiddo on your ticket you can be sure that he'll grant you access, she or he is so easy to trick,

and keep that in mind that even though those are enough some riot employees might want to ask more questions.
so in order for this method to work you will need something called LUCK too.
