Promotion bosh dishwasher.

I bought a bosch dishwasher and as part of promotion when you buy a dishwasher you get a R500 gift finish dishwasher products. Dont know if its just a **** because I did send proof of purchase and did receive a email saying thank you for purchasing a bosch product your gift is on its way. But I didnt receive anything. And the promo ends 15 may. If this promotion is not true dont mislead people. Thank you.
