Vumatel has not refunded me for a service they could not provide through Supersonic

I paid Vumtel for a service through Supersonic on the 28th of April 2021 , they were unable to fulfil the service and I requested to cancel and refund my installation. I followed the procedure by emailing supersonic as per their website. I did not receive any feedback , I ended up calling supersonic and they advised me that Vumatel takes a few months to process refunds , which I accepted. It has been over 5 months now and no refund or feedback was made. I tried reaching out to Vumtel but their is no contact number or valid email address. Supersonic is no help as they just inform me they have to reach out to Vumtel for an update on my refund. This will be the second time Vumatel does not refund my household for a service they were unable to provide through Supersonic. In the times we live to day maybe the amount is insignifiacnt to them but to my household every penny counts , I am very disappointed with Vumtel considering I have a ongoing fiber arrangement with them through Afrihost which gets paid every day on the 1st. So it is easy for them to take money but not return it. I have no choice but to continue with them through Afrihost as I work from home. Many people are struggling in todays times and for Vumatel to not show any companion to many of their customers is really disgusting.
