Otsiele Boikanyo not customer focused

I am honestly disgusted in the way complaints are handled at Makro. A customer is just a number. What is the purpose of having a makro card, Otsiele Boikanyo? You have told me you cannot backdate birthday vouchers after I told you I have never received one in all the years I have been with you. I asked that you email me due to the 11 hour time difference between nz and sa but you keep calling me. I may not be a big spender but you claim to offer birthday vouchers via sms. If you can't backdate then surely you can issue a voucher to the value of what the client has missed but you just don't want to.. I will be buying my camping equipment at tento. Big loss for your company
