To her more than one million social media followers, The Apprentice winner Karishma Vijay provides daily updates on all aspects of her ‘chaotic life’.

From her excitement about her forthcoming wedding and new product launches to behind-the-scenes chat about The Apprentice and her flourishing relationship with Lord Sugar, nothing appears off limits.

She proudly took to social media to reveal her skincare business Kishkin had clocked up £250k in sales in just 72 hours (as reported by BusinessCloud) after the 29-year-old was crowned the winner of series 20 of The Apprentice.

However, her business has been less forthcoming in providing updates when responding to complaints from a growing number of unhappy customers.

Out of Kishkin’s 80 reviews on the online platform Trustpilot, 62 per cent gave the company the lowest possible one-star rating, compared with 20 per cent who awarded it five stars.

Across all 80 reviews, Kishkin received an average score of 2.2, which Trustpilot describes as ‘poor’.

Most of the complaints have focused on the quality of Kishkin’s customer service – described as ‘awful’ and ‘terrible’ by some – as well as the length of delivery times.

Many customers have reported significant issues with their orders, unreliable tracking information, processing delays and items not arriving as expected.

Several people have complained about the quality of the company’s customer service, claiming their emails and messages have been ignored.
