VFS Global Ignoring My Request for a Refund

At the beginning of June, my wife and I submitted applications with VFS Global. Before submitting applications we checked the VFS website and phoned the call center to find out the exact documents that were needed for the application. Sadly when we arrived at VFS, they sent us back 4 times because of incorrect information that they had given us. This resulted in paying and submitting a wrong application in the process. However, we ended up paying again to submit a correct application. Towards the end of June I initiated the process of the refund through the website. There was no feedback at all. After calling The VFS call center staff said I should email their supervisor (***) but my emails have been ignored and this is now more than 2 months of waiting. I'm not happy about this because I need my refund.
