Refund process

I took a contract phone on Saturday and cancelled the contract on Sunday unfortunately the store was closed and I went there Monday, it was a hustle cancelling the contract with rude store manager , I had to request for the store owners details until they provide me with the branch manager details and approved my cancellation. A month later they deducted funds from my account and I requested a refund which I'm still waiting for and it's almost a month now with no fund. They advised they waiting upon Vodacom to refund my money back. I have not heard of an electronic refund that takes a full month to process
