Budweiser complaint: Blocking truck and guys in the truck

I was leaving the driveway from HEB store. I had my blinker to turn left. I though the distribution truck was turning in towards the store. I was going to turn left since no traffic was coming but instead he moved up and blocked the opportunity for me to turn left. A lot of traffic came through And I raised my hands to him as what are you doing he laughed. So as traffic finally slows he once again pursues to move thinking he was turning into the driveway. No he was making a u-turn whicH now forces me to Move back because this in not an area for an 28 wheeler to u-turn. I get angry I flip the bird and both guys laugh and the passenger in the truck mouths out words to me and flips the finger back at me. I hope you have better driver trainer than that. Their response was uncalled for. Cab I only remember the first 3 s. License plates from back of truck is ***.
