Dont trust Pick n Pay

We recently bought a Bosch washing machine at Pick n Pay Bloemfontein. Together with it was a promotion of Omo liquid washing soap for 12 months free. This had to be collected monthly. We live in a rural area where there is no Pick n Pay. So we drove to Wolmaransstad to collect it but they refused to honour the promotion. They said only a hyperama. Actually the promotion is not worth the paper it is written on. Dont promise and refuse later. Disgusted!!!
