OP why are you not providing the required documents for the to process your request, don't you know thst as long as you make use of a kyc casino, they will definitely request for your identity and some information about you, you're the one delaying yourself here i think because they cannot shift ground for you except you comply with them, giving me them just your electric bill or other required documents shouldn't be a difficult task to you, maybe next time you will learn not to use a kyc casino and choose the ones that don't request for such.
The OP gave all these bills, bank statements - everything the Stake support asked as i understand. If he tells us the truth - i don`t see any problems with KYC - he gave enough information for it. The moment i`m interested in is why @stunna doesn`t post here, he usually answer when someone has problems with the Stake.
PS. The easiest way to KYC in such situation - video call. In such verification the OP can show his ID and bills.
