Missing Takelot voucher with upgrade

Vodacom contacted me regarding my upgrade on the 1st of April 2021. Part of this upgrade package included a R2000 Takelot voucher. I agreed to the upgrade and the upgrade fees were deducted from my account the next month. I received the educational vouchers within the next few days in the month of april but no Takelot voucher was received. I followed up via the Facebook messenger service and they investigated to let me know that I should receive the voucher within 15-30 days after the upgrade is completed. I waited until the end of May. I then followed up on the 1st of June. We are now on the 6th of July and they still dont have feedback for me. All I get told is that “I will be contacted when feedback is available “. How is this acceptable? 3 months to resolve a query of just sending a voucher code to an email address?!?!?
