Continuous promblems with Pick n pays and Bp's collectable promotions

Collectable promo is very frustrating when you have to keep till slips to claim your collectable car because of Pick n pay's "network issues" i have not been recieving my sms's and when i called numerous times and used their whatsapp robot and lodged inquiries with them they are asking me to provide a till slip i do not keep till slips so they said i must drive to Bp or phone them to get a copy this is not my problem its Pick n Pays problem i did my part by filling up to the required amount and swiping my smart shopper and Bp cards i followed their rules now they want me to use my airtime and fuel to redeem something that is rightfully mine.
