****py service by Vodacom and Finrite

This company has been stalling with my refund for almost if not more than 3 months already now. This is what happened, I took a double cellphone deal with Vodacom more than 2 years ago, after a few months of paying I realized that they were overcharging me for the other cellphone, I contacted numerous Vodacom outlets to assist but they were unable to and cited that I needed to contact the store I have been assisted at but it was hard for me to get there cause it the beginning of the lock down but I eventually managed to get to them (Vodacom canal walk) sometime early this year. I asked what happened, they told me said the agent that was assisting me loaded an incorrect debit order (which is far higher that what's in the contract I signed). They told me then logged a call with Finrite (the insurer) but the issue continued, I went back to them and asked them what is happening? why is this not resolved? To my surprise the lady that assisted me told me that no incident was logged. So I had to ask them to log another one in October and they logged it (ref ***). Ever since then I never got any feedback from them, I every time I call them they tell me they are waiting on Finrite, so they also asked me to call finrite as well, off which I did numerous times they don't pick up. Can some someone urgently assist with this issue ASAP!
