Unresolved Refund Issue for iPhone Purchase from Vodacom Website

Corrected version with improved grammar and punctuation:

On 03/01/2023, I purchased an iPhone 11 64GB online from the Vodacom website using my old card before it got broken. After the card got broken, I obtained a brand new card. When the phone was delivered, it wasn't what I expected, so I called Vodacom to return it. The RAM courier company came and collected it. According to Vodacom's refund policy, I waited for a period of 14 days, but there was no sign of the refund. I even called them and provided the supporting documents to release the funds, but they said their team was busy with it. After some time, they informed me that the money was transferred to the old card, and I should consult with my bank. I went to the bank, and they said it is impossible for an old card to receive the money. They mentioned that Vodacom should link the old card to the new one, and it's not a difficult process. I returned to Vodacom and explained what the bank had told me, and they said they would look into it. Now, it's already August, and I've been waiting for my money since January/February.
