Eskom electricity coupons by vodacom

I purchased an eskom prepaid voucher via the VodaBucks store on the VodaPay Superapp. Having followed all the instructions to redeem the coupon, only to find that my municipality cannot be found on the USSD redemption journey. Totally frustrated and not knowing how else to make this work, I post here. As I write this, the voucher is due to expire in two days. Vodacom, please help me and also make this experience better for other customers
