Please could someone from BT contact me, as I still have not recieved the vouchers.
Have you claimed it ? it needs claimed manually like a BT reward card, however if this is from last year the window to claim might of closed, looking at past offers any order from December had a cut off date of April.
You need to go to Claim your Marks and Spencer vouchers. and fill out your order details, if successful the voucher will be sent to the address the services are active within 45 days.
