Sorry I'm late to the party
The worst customer support experience I had in almost 40 years in helicoprter maintenance was with Rogerson Kratos. It was everything stated above and more. At one point when I finally got someone who would talk to me, almost impossible most of the time, they actually told me they couldn't find the unit or their work order. I was calling about a close to $30K repair estimate they had sent me. I had to get the shipping data and read to them who had received it and when it was plunked down on their doorstep. I cringe as a taxpayer every time I see their name mentioned in a government contract. Have a great day RK.
