It turns out these people are not legal distributors of Jessica products. The products are not working as they should so I can only assume they are fakes.
Customer service is yet to respond to my request of replacement genuine products but I'm not holding my breath. They didn't come back to me when I Iast complained in July.
You can't sell branded products and not sell the genuine product that's 'fit for purpose'. If they are genuine they are really old and therefore not fit for purpose.
You get what you pay for.
