Pathetic Service

ZERO STARS!!!!!!!! App failed on 26th November. Could not redeem voucher, lost out on sale. Whole day same issue. on 27th November, say's voucher has been processed, but the app could not show me the voucher. Contacted the chat box assistant who said they will return the voucher back into miles points + compensation fo the error and bad experience. which is still not done. Phoned Discovery today, 29th November to follow up on this request, been put from department-to-department cos no one knows who deals with Discovery miles...3 time in Vitality department, and they didn't know that its their responsibility. 30min on call, time taken from my normal job to try and resolve what is clearly Discovery poor quality of service.
