I still do not recieve birthday vouchers

In the past,more than 5 years ago, I have received a birthday voucher from Makro annually. The past 5 years(this year included) I have not received any vouchers, even though the call centre claims that they have been issued to me. I have confirmed my email and contact information, and still not received anything. It is also claimed that the voucher was used in the previous 3 years,it has only been used by me the past 2 years after I previously complained on Hellopeter, but definitely not by me the owner of the card specified at the other instances. It has also become a habit to only receive a voucher after complaining on Hellopeter, and after Makro telling me in their responses every year that the problem has been fixed. The problem has definitely not been fixed as I still have to highlight it every year now. I have been a regular customer at Makro, since Mr Jocchims was at the old Milnerton Branch, but it seems as if they only offer vouchers to clients that do not regularly purchase there. So much for loyalty.
