You need to contact the service provider directly for rescheduling your booking with them. You will find the contact details in the SMS notification received by you. Rescheduling is subjected to availability and the Service Provider may ask for additional charges. 

As of now, Wellnessta do not provide appointment rescheduling option. However, Wellnessta Support Staff will be happy to assist you in finding if rescheduling is possible or not? Please call our call centre or send message on WhatsApp.
