Mr Delivery - Voucher erros

Been struggling for over 2 weeks and all these so called agents can't resolve my issue with the 2 vouchers which was provided.

When I attempt to use the vouchers, I keep on getting erros. Screenshots has been sent and all the relevant info has been sent to about 4 different agents and none could resolve this issue.

They can search on their system with my email address for the vouchers which they have issued cause both isn't working.

Do not contact me if this can't be resolve, I just want my vouchers to work as you have been an inconvenience on the 2 occasions hence the vouchers was issued.. Now its a convenience for +2 weeks

RESOLVE THIS ISSUE!!
