Unresponsive support and poor communication

I logged a case last week Friday to the finance/accounts team with regards to my account and when I called in I was told that the turn around time is 24 hours but till today I have not received any communication. When I do call each person I am being transferred to tells me different turn around times like they work for different institutions. I’m not happy with the service I’m getting from Milpark. Any response is better than total silence!
