Mondo - Refund

I have ordered a phone in 2022 and it arrived in September and the first payment went off in October. I was advised that there will be a once off fee of R149.00 which was taken with the first instalment. On the 03/06/2023 another R149.00 got taken out and called the customer service line on the 14th of June 2023 and I was advised to send proof which is my bank statement and I did that and I haven’t got any feedback or response and I reminded the lady I was speaking to on the 23rd of June up until now I have received the refund.
