VFS South Africa not reflecting online payments early

I recently made an EFT payment on the VFS online application platform on 17 March 2018 as this is a requirement to be able to schedule for an appointment to submit work permit documentation. Up until now i cant make an appointment on VFS online plartform as the payment has not reflected. This is not what i expected from a company that has global presence. I would appreciate if the issue is resolved so that my eligibility for the work permit is not compromised due to late application.
