I g bought an iPhone off marketplace and when I received it it was locked how can I get around this because the seller done. Blocked me
You can't get around it. Activation Lock is an anti-theft mechanism that is designed to block thieves, fences, and anyone they might sell a stolen phone to, from using a stolen phone.
If the sender blocked you, that is a very strong indication that they scammed you – that they knew that they were selling a phone that was not properly prepared for a new owner, or, more likely, a stolen phone.
You can only (1) learn from the experience, and (2) report this seller. If you can get your money back, you will be very lucky; most people who are scammed in this way don't get it back.
