Coinbase verification issues

Having Coinbase login errors for 2 days. I sent them all my documents including my water bill, my passport, driving license, bank account and ID. Firstly, they sent me an email saying account all is fine. Next day account under review. Then unverified account! And now I cannot login to Coinbase. I have heared that Coinbase verification was harsh and takes long time but this thing they do is not only exhausting but also very untrustworthy.
