Worst experience with Baby Soft SA

I have had the worst experience dealing with Baby Soft SA.They ran a promotion and i received a voucher to redeem when purchasing Baby Soft toilet paper ,i went to Dischem for my shopping and was told the voucher is invalid In November, they called Kimberly Clark/Baby Soft to report this they asked me to email all the details to them and they will rectify this error.Its almost 3 months later,i have been receiving new codes from them to rectify the incorrect one and none of them were authentic, I have driven to driven stores like Dischem, Checkers PicknPay like a person who has nothing better to do only to be told all the codes sent directly by BabySoft to me are invalid.I have been back and forth with them and to date no consideration and respect has been given as a loyal client of theirs since I was born as my parents introduced us to their products. I am definitely going to stop supporting such business that exploit their clients and have no care in the world just because they believe losing 1 customer means nothing.Well a new era has begun.
