Refund bridge of contract

I had placed an order for a hp laptop only to find that it’s not as big as the one being advertised. I then requested a refund. I had spoke to Mohamed I told him I was unhappy with the product and I was going to return it. I put my refund the same day I received it the 4th of May. Their policy says it takes 10 days to be returned. But 3 days passed nothing no email to inform me that they are sending the delivery company to collect nothing. I called spoke to Rania she assured me she will help me through this then nothing. This was the 8th of May. On the 11th of May I spoke to Lalia still nothing. Again I follow up I got Ebtsam who requested proof of my claim I sent her. Still nothing. Then I’m informed by another person from their team saying they had an issue and it’s now the 9th day so meaning they want your refund to be forfeited purposely. They don’t stick to their own policy which is bridge of contract. Weeks has passed I involved payflex as I bought it through them to reach out to them and get this resolved. It was after the 2nd attempt of payflex that Revibe says they keeping me updated and they working on refunding me. Payflex then said this is sorted n torched me aside like that. I requested that my account not be debited as Revibe team has not refunded me nor collected their device. So they processed debating my account o removed my funds. This will affect me negatively as Revibe wants more money from me yet they are not fulfilling their agreement. South Africa should cut ties with such companies. I tried to email the co founder of Revibe nothing. I am writing my exams now in June and still I have to chase for my money/ device. This is super frustrating can I have my money back and come collect this old device.
