IONTOP****SIS SA - undisclosed exorbitant costs once u get started, no proper paperwork

This lady S****ha, founder of the business does not disclose all costs upfront, once u invest the expensive treatment you are hooked to continue with her maintenance treatment which she does not tell you the costs and duration. You have to beg for invoices and when she does send it doesnt have a company registration number. She doesnt advise on cost plan upfront in writing. ********* and Unprofessional. I was blocked from Whatsapp for raising these issues, my child's treatment was terminated when i questioned these costs and I am still waiting for a valid invoice for the treatment expense which is needed for tax submission. Pathetic Service. I am wondering if this even is a legit company. Please ask for full cost disclosure before u start any treatment with this company.
