Tom Sandoval Rips Doubters, Says Raquel Leviss Is In Mental Health Facility

Tom Sandoval is ripping anyone doubting the sincerity of Raquel Leviss' mental health treatments ... he says she's really getting help and isn't in some swanky resort.

The "Vanderpump Rules" star called out a couple former castmates by name Tuesday, tearing into Peter Madrigal and Dayna Kathan for casting doubt on Raquel's whereabouts.

Tom was in Van Nuys and grew agitated when paparazzi asked him if he had seen Raquel in Arizona ... Tom says she's in a mental health facility that doesn't allow visitors or phones.

There's been speculation online Raquel is really at a Miraval Resort and & Spa location in Arizona ... but Tom says that's all BS and he seems peeved by all the rumors.

Tom says he went to a resort for some R&R and solo time in the wake of the "Scandoval," but he's adamant Raquel isn't living it up in a posh resort and is truly getting the help she needs.

Remember ... Tom blasted Miraval last week after the resort's social media team played into the speculation that he was going to be there, possibly to see Raquel.

Tom and Raquel have been getting tons of backlash since their cheating scandal rocked the show and blew up his 9-year relationship with Ariana Madix ... and they've both been struggling to keep their sanity, with Raquel seeking treatment as a result of the fallout.
