Takealot voucher not allocated

On April 2022, I renewed my contract and the deal included the Takealot voucher and I was told that I will receive it after 2 successful debits. The third and fourth debit went through, still no voucher. I've been making numerous calls to follow up on this issue only to be told that its being escalated, I'm tired of making calls, please load my voucher because I'm honouring my monthly payments.
