Disappointing customer service regarding the Vodacom Kwika device

If you are thinking about purchasing a Vodacom Kwika device for your business don’t. I purchased the device online but they were out of stock and I required the device urgently. I then went in store and purchased the Kwika device meaning I needed to cancel the device purchased online. For some reason since November 2022 vodacom is unable to distinguish the two devices from each other and I am yet to be refunded my money for the device. I have called numerous times, provided the necessary documentation that they don’t tell me I need until I have to call them and have a dozen reference numbers. How are we in 2023 and I am yet to receive my money or any sort of direction from anyone. Honestly disappointing customer service from the number 1 network company in South Africa
