Hopefully, Stake will accept your documents this time for the address verification. You should prepare yourself for the next step (source of funds verification) now. There is no option to create pressure on Stake team by any method to make this process easier for you. All you can do is to prepare the documents which they are requesting from you. I would like to suggest you to submit a complaint on CasinoGuru for having a better communication for the process. Another user had created a scam accusation here who was struggling with level 3 and level 4 verification of Stake. He was able to verify after trying for almost ~6 months. The user got good help from CasinoGuru team. You may follow his case here: Stake Casino - Player’s withdrawal delayed due to KYC process.
