Has anyone been approved with Guardian One Net?

Hello all, I have surgery date but I am not sure if my insurance company will approve me. The funny things is I called them last week and they said that they didn't have record of me having any type of WLF surgery. I don't know if it was because we were with Guardian Alliance and now it is Guardian One Net. I am hoping that will be a good thing for me to get approved. I am just so nervous about this. My date is July 2 and my doctor asst made it seem as if VSG has not been getting much approval from insurance companies. I have been reading some of the post and I guess it is a new procedure. Well I know that I don't want to have gastric bypass done. I don't like the way that it is making my friends look. They look really sickly and are losing hair. Anyhoo if anyone can give me some information I would appreciate it. Thanks  Chas
