Bad and inefficient service

The Discovery offer of an Apple Watch to qualifying members is an absolute painful exercise to implement. Payment of initial fee was reserved via discovery card then reversed unilaterally. On attending at iStore to collect watch was told discovery should have sent an e-mail with a pin together with voucher code. Tried contacting vitality call centre however forced to wait 20 minutes with no answer. Then received e-mail pin at 23h00 which pin then expired at 00h00. Wrote to vitality to explain why they are not fulfilling the offer as marketed on website still awaiting a response
