If a customer needs to cancel a Glamsquad appointment, it is important to follow the cancellation policy outlined on the Glamsquad website or app. Typically, customers can cancel their appointment through their account or by referring to the confirmation email they received when booking. There may be a time frame within which cancellations can be made without incurring a fee; for example, cancelling a certain number of hours in advance may allow for a full refund. However, cancelling too close to the appointment time may result in charges. Glamsquad strives to provide flexibility, so it is recommended to review the specific cancellation terms before making an appointment. For the most accurate and detailed information, it is best to check the current cancellation policy on their official website or app.
