BE AWARE of the Scam by Frantz G Glasz -- This Is My Real Experience…read more
Hear me out you'll see why he's extremely evil, cruel, manipulative, someone you want to avoid at all cost.
I purchased 10 private 1:1 tennis lessons from Frantz G Glasz, but only completed 4 due to extremely poor quality, unsafe instruction, unprofessional behavior, and his ongoing refusal to issue any refund despite multiple attempts to resolve the situation.
1. Suspicious payment methods & refusal to issue receipts
Between Oct 2022 - Dec 2022, Frantz required the entire $1,000 payment upfront, and cash-only. He refused Venmo, Zelle, or any digital payment, and refused to provide a proper receipt. I had to insist multiple times just to get a basic text message confirming payment -- the entire arrangement already felt questionable and unprofessional.
2. Unsafe instruction that caused an injury
In my 2nd lesson (10/22/22), due to his lack of guidance and proper coaching, I suffered a wrist injury that took 2 months to heal. For a total beginner, his careless approach was unsafe, and he showed no concern or accountability. Across all lessons, he put in minimal effort, offered almost no true instruction, and showed no intention of actually teaching.
3. Lied about court reservations & wasted my time
During my 4th lesson (12/2/22), he claimed the court was reserved, but it was clearly not. When I said I needed to return to work since no court was available, he insisted he had "other courts reserved" and told me to get in his car.
I trusted him -- and he drove me around San Francisco for nearly an hour with no reservations anywhere. The lesson never happened, and he left me far from the original meeting point afterward. He lied repeatedly, wasted my time, and acted irresponsibly.
4. Unreachable afterward & defensive when I raised concerns
After that day, I tried to schedule my next lesson, but he ignored my messages. When I expressed concerns about the poor quality of instruction, he immediately became defensive, rude, and dismissive, showing zero interest in understanding or improving.
His polite-sounding public review responses are performative -- in private he behaved very differently.
5. Inappropriate personal comments during lessons
Throughout my lessons, he asked inappropriate personal questions (e.g., whether I was single) and talked about his own dating life -- which was unprofessional and made me uncomfortable.
6. Refused to refund unused lessons
When I requested a refund for the remaining 6 lessons (lessons 5-10), he refused to refund even the 5th lesson, which had not happened yet. He took advantage of my trust and acted with dishonesty and zero professionalism.
7. Denied ever teaching me in public after I posted my review
Over the past 3 years, I have attempted to contact him for a refund, especially given the unsafe coaching, injury, and unprofessional conduct. He never responded.
After I posted an honest review about my experience, he publicly denied ever teaching me, which is simply false.
This appears to be an attempt to protect his image rather than address legitimate concerns.
Bottom line
I trusted him because of his 5-star reviews, but my real experience was unsafe, manipulative, dishonest, and far below what was advertised.
This whole process has caused me an unbearable amount of pain and has had a deep, lasting impact on my mental health.
I was left with a very clear impression of his character: someone driven by greed, ego, and self-interest, with no regard for the impact he has on others. His actions felt deeply selfish, cruel, and manipulative.
Avoid him.
He took my money, provided unsafe and unprofessional lessons, and refused any accountability or refund.
