Anthony without seeing the swing it would be difficult to know for sure, but If you are consistently going left, assuming the ball is flying straight that way and not hooking then it sounds like there is a move at or near the top of the swing. My suggestion would be to try and hit several punch shots with a half swing to ensure the ball is flying straight then adding length to the swing and follow through until you feel the move that is causing the ball to go left.

There are many of us PGA Professionals that would be able to work on your swing online or in person. If you continue to struggle reach out and take a lesson or two.

Thank you, I will try and practise that and see how it goes

Had the same issue. Went to see a PGA teacher. Told me that I was not lining my shoulders with my target. Helped. But like said before, hard to correct online. Recommend seeing a PGA instructor for correction. They can find your particular problem quickly and correct it.
