update -
Rejected again with the following response.
"Level 3 is rejected, the customer sent a bank statement, they need to upload a utility bill for the last three months and proof of payment of that bill for each month."
The above is not true as I supplied them with a bank statement and a bank reference letter. Both stamped.
I am not going on that utility bill merry-go-around again.
Ive recreated the complaint on askgamblers with this new information. Hopefully they accept it.
I believe that in this forum there are people from your country who use stake and are verified at level 3, so you should ask them what documents they used to verify their accounts at level 3 and get the same document in your country and deliver it to stake. because it may happen that the documents you are submitting are not valid in the stake. Also you talk about 6000 USD, did you deposit the money through your bank account or was it through cryptocurrencies? and which country had you traveled to when they asked you for level 3 kyc?
The OP is clear enough about this case and a more reason why we should consider our accounts when we are leaving the country we registered them from for the security of the account and the safety of our funds. Well, people are smarter than each other because, I always consider where I have huge money before having my IP address changed for whatsoever reason and I make sure I do not use the VPN. This is because these days many companies frown at the change in the country of residence/registered IP and it could be problematic for the customer because if they could be complaining about the use of VPN, why can't they complain about the change of country's IP even if it's not a VPN?
No one can blame them as they are protecting their customers and company from cheating and adhere to their ToS. As it is now, it's over a year for this guy, I feel for him, however, we should learn from his predecament. Perhabs we can inform our casino before leaving the country if that would save us the stress because indeed to pass the verification being asked of this guy in some countries is difficult as the system of bills payment and others are not always the same for every country, even the government is not helping to make some bills provable/acceptable.
