SASOL Rewards - ***** cover up/*****ing!

I am using the SASOL REWARDS card and from December had people *****ing my and using my reward points on vouchers. Reported to Sasol in January en was contacted by two people and via email. Initial points credited again. But is still happens and repeated attempts to get hold of these employees with sasol emails failed. Calls to Rewards card centre useless NO-ONE there replies, nor several demands by me for managers or marketing dept heads to contact me regarding this ***** materializes. Best they do is have ***ing bot reply with yet another case number stating falsely customer contacted, or case resolved or credit passed. LIES! It is IMPOSSIBLE to get a f human in SASOL to call me back and explain how my rewards is hacked. I am convinced employees are involved and this must be happening to hundreds of customers. NO responsibility or care by SASOL. The rewards is a ****, rather use BP or Shell rewards they have integrity. I have sent many emails explaining exactly dates, numbers and values how my rewards are ******. SASOL *****S! Head of marketing, your head is stuck in sand!
