Refund request

For the last week I have been trying to get a refund for my mobimoney account ,which I settle on the 17th of February but they have failed to help me. I have called the relentless but their consultants either go mute on the phone or hang up. They are unprofessional and have no telephone etiquette none whatsoever. The last one that I spoke to was Thembakazi on the 07/03/22 after haveing taken my details she just went mute on the line. When I request for them to call me back they do, but never talk on the line. I am very disappointed and frustrated with their service or lack thereof.
