Data request to Vodacom they refuse

I have night owl data that I am not using, and asked Vodacom to transfer it to my daily data, as I am working from home, and need to use my own data, they just refuse to do it. I paid that that data, and cannot stay up till after 12 at night to use it, and then get up early to do my daily work. I think in this time they can accommodate people that need data to perform their work from home. I have never requested this in the past, and know I loose my data that is not used, although I have paid for it, so in essence it belongs to me and not Vodacom.
