I feel scammed...all times before it was instant so when I know this, I would never use this service. Will close my account when funds released..
And guess what support and my ticket. 30 hours with no reply!
You shouldn't use blockchain.com, as it is one of the worst service providers in the ecosystem. They are not scammers, but they are inneficient, unsafe, require a lot of KYC, do not respect privacy, etc...
You should look for big exchanges, like coinbase, binance, kraken, bitstamp... and once you buy the bitcoin using your credit card/bank transfer you should immediatelly withdraw the money to your wallet (It is best to use a hardware wallet, such as ledger or trezor. I highly recommend that).
