Goldredash

Hello, I played this game in 2018 and I was on the red server, but now everything has changed and there is only gold and silver. I pressed gold and only have my Charmander pokemon. It says the date I joined in 25-03-2018 (for red in gold) however I barely have any pokemon with lots of pokemon on my Pokedex. This means that data got erased and all my grinding that I did back in the day got erased. I came back cause I wanted to continue from where I left off, however, I now Cannot do it as he data from my game has been deleted. I have 2 ms medallions in my inventory for some reason as well. Also, I cannot log in to the silver server for some reason, it says invalid password/username, even though I use them to login into the gold server. Username GOLDREDASH. Would like some answers and possible compensation if you cannot fix my problems. Regards, 2018 PRO player
