Openserve not completing order

on 21 April I upgraded my fibre package with MWeb/Openserve . I was advised that the order had been sent to openserve that day. Two weeks late the order shows as being completed yet I am stil on my old package. . I urgently need the upgraded package to be able to work form home Email follow ups with both the Openserve office and the area manager Philip Bremner yields no response. While I was warned it COULD take up to 14 days, that is now well past that time
