Refund take over 5 months

It has now been 5 months that i have been trying to get my refund back from vodacom rewards department.I have escalated severals times and sent several evals. I have tried logging a complaint but u cant over the phone they say u have to send a email. This is my second hello peter review .Please can someone help me .Ombudsmen is my next option but they need a complaint reference number

Which im even struggling to get.This is truly sad and just a huge injust for me that has been a loyal client to vodacom for over 20 years. The fact that vodacom can get away with treating there customers like this is complete madnest and if this is a taste of how service from them will be in the future i feel sorry for there customers. This is my third complaint over a span of a few months and im still waiting for vodacom to contact me after there automatic responce to this review. Shame on you VODACOM shame on you.
