First of all , you need to show 500k in thai baht or a relevant amount in another currency in your personal bank account , remote pass isnt a bank account and its probably why they rejected you if you arent egyptian , but if you are egyptian they would reject you anyway without a reason , i know a couple of friends that got rejected even they may have applied with stronger documents than i did , but i got mine from another country back in october
it happened once with me that i didnt have the tm30 and i had no clue what was that doc , they asked me to bring my landlord with me to immigration and the officer told me something like tell her that he is asking her to come or he will go to her , once i told her she was terrified and i helped her out by doing it in another province cuz i was leaving any way and got my new tm30 from the hotel there
If you stayed in any other property in thailand even for 1 night and they did the tm30 for you "and they usually do" then you have to ask your landlord to update it for you again , if it's the same place and you didnt stay in a hotel at all , you are good to go ,
Though if you still live in the same place after you are back just go with your old tm30 on the extension date and give it to the officer at the immigration where they do tm30s and tell them you stay at the same address and you just wanna update & they will give you a new one
