VFS global refund not received

I was at VFS global in Rustenburg and they told me to change my application form, which resulted in an extra payment. They assured me a refund of the old one. I am already losing R250 rand because of this, now the refund is also not done more than 30 calendar days have passed. When calling the helpline they play a lot of music and when they answered eventually, I was told by Refilwe that they can only assist me at the VFS centre. Eventually when I refused to accept this as a solution, they took down my number and email address and I am still waiting for them to contact me. The supervisor at Rustenburg gave me a copy of the refund application but did not sign it, which he should have done, making the process even more difficult for me know.
