PLEASE HELP ACY have cost me $70 000

Has anyone had any data feed problems with ACY Securities.The Acy dirty data has caused their own platform to malfunction. My proven Ea can not function on ACY dirty data. ( it works on everyone else platform.) I am getting two four hour bars on a four hour chart. (There is only meant to be one, obviously.) I was on Zoom meeting with their representative and when he saw the problem live, he left. They will not even talk to me now. I am trying to go through AFCA but ACY have denied everything. They said the zoom meeting never took place. They have stated that there own data is not their responsibility. . Acy have cost me my business. I can not believe how they have ignored me, way before I went to AFCA. Please help
