I recently received a voucher for a day spa package and when trying to book in was asked to do so via text message as requested by the voicemail. I sent a text requesting a weekend appointment to redeem my voucher and received the following message "We don't open Saturdays for gift vouchers as staff don't want to work those days or after 4pm.
We look forward to relaxing you when you come in. 10am to 4pm Tue Thur Fri"
The business hours online clearly state they are open on Saturdays and evenings so why should it matter if you have a voucher. I am not at all impressed with this response and the fact that all correspondence is via text message.
