Vodacom PicknPay voucher

In August 2021 I took out an online Vodacom cellphone contract that came with a PicknPay voucher. I thought great deal! The phone arrived some days later and subsequently some messages from Vodacom about the phone being activated and such. On the 2nd of September I received an SMS with a voucher number and I thought it's the voucher from the package. I tried this voucher several times at the store and every time it secluded. Today I call Vodacom about the voucher and they tell me that the sms can't be from them and further accuse me of lying about the message. This is after I had called several times on Friday to resolve this issue and they knew nothing about said vouchers or how they work. I continue to call PicknPay thinking they could help but no luck. Vodacom after a lot of back and forth tell me that the number they have assigned me for the contract is not registered nor is the number that I have had for over 10 years! Also that my name does not register on their system nor is it associated with both numbers.

The consultant tells me that I must contact the person who sold me the contract and have them sort this out because they can't help me.

Vodacom Customer Service!!!! Does not work! I've yet to have an actual issue resolved by them!!!

To say I'm frustrated is an understatement.

Thanks.
