Poor Service From Openserve

My fiancé and I have recently moved into a new place and I requested a transfer from my ISP. I placed my order and I understood that installations would take place after the 'freeze period' which was, according to my ISP, from 11 December 2020 to 11 January 2021. After the 'freeze period' I followed up with my ISP as to when I can expect the guys from Openserve to schedule an installation date and they requested that I provide them with proof of residence (which I did). They couldn't provide me an expectation date so I then went on to ask my ISP if it is possible to escalate the request from Openserve as myself and my fiancé work from home, in which they then informed me that it has been escalated. It has now been 6-7 days without any sort of feedback from Openserve to my ISP and I have now exceeded my budget on purchasing mobile data in order to work. At this point any sort of assistance would be highly appreciated. For the record, my issue is NOT with Axxess.co.za. Openserve's poor service and lack of feedback is the issue. There is no way of contacting them directly, therefore I have to do it through my ISP and this platform.
