So disgruntled, they’ve even started a private Facebook group - titled Brittany Dawn Fitness Complaints - to share their criticism.
‘We’d go weeks at a time without communication,’ angry customer Melina Brunson told US news station KHOU.
‘There would be something I’d need to know that morning, and I wouldn’t hear back from her until that night, maybe until a week later. I mean, what kind of access is that?’
Another upset client said: ‘It took her like over six weeks to reply to me. I just can’t imagine her stealing all this money from people. It’s not OK.’
And it doesn’t stop there, with Better Business Bureau is handling even more complaints about the diet coach.
‘I purchased three online plans from Brittany. The first was a month long training plan advertised as individualised, when in reality it was the same exact plan every consumer receives,’ reads one complaint on the website.
‘In addition, the plan included weekly check ins to ask questions, receive guidance, and adjust macronutrients with the promise of a three-day turn around. Not only were the responses from her well beyond the promised time frame, they also didn’t bother to answer any questions or address any of my concerns. They were generic responses, like “doing great, keep going girl!” and the like.’
It’s further been claimed that Brittany blocked clients wanting answers about unpaid services on her social media accounts, as well as deleting negative comments.
But with the backlash gaining such momentum, Brittany has been forced to answer her critics - taking to YouTube to film a teary apology.
‘I ran too fast for one person,’ she said in the video. ‘At times it got extremely overwhelming, and I took on more than I should have and for that, I take full responsibility and I am sorry.’
However the video prompted more anger from disgruntled clients who claim she could’ve pulled the pin on the program, instead of accepting more clients and taking people’s money.
‘You’re not the victim here,’ wrote one critic.
