Makro Unused airtime

I bought 6 airtime vouchers with Makro and when I was about to use them the message said the vouchers were used. I then called vodacom who then told me that the voucher numbers were re-generated and I should go back to Makro and ask them for new ones. Makro then send me from one pillar to post and eventually got two supervisors that called vodacom to confirm my story and was then send to the General Manager whom was not available to assist me only to be assisted by a rude Accounts Manager named Elsie Cloete. I started this process in July 2019 and to date no one is willing to assist in Makro.

The amount that I have lost is R 1650.00
