What is your story of not being able to access your Bitcoin wallet with Bitcoins in them.
What have you tried to retrieve them?
I have never lost access to my Bitcoins, and I guess thats because I did proper research before I started making use of Bitcoin and other cryptocurrencies.
The first wallet I used required that I back up my wallets, same thing with other wallets I made use of then the BitPay wallet and Blockchain, and I still use these two alongside other wallets. I started using it on my phone and there was a time I had to factory-reset my phone, and after that I was still able to load my wallets using the backup phrase. So I have never had such issues. Thats why its very important that anything you want to get involved in, you do proper research on it.
