Vodacom Fibre

I logged a SR for my Fibre on 07/01/2019 as my Internet appears to be intermittent. Each time I call I am told a senior technician is busy with the SR and that this person will make contact with me. Suddenly I notice all my port forwarding no longer works and some sort of reset has been done to the Nokia router, but this has not been noted on the SR. It would have been courteous to inform me that I had to forward my ports on the router again. It is now 25 days later and each time I call they want to reset the services and send an email to the senior technician handling the SR. I have not received one call since the reference was logged and I am extremely frustrated at how this has been handled. It is extremely poor service. Today, my router lost connectivity showing "authentication failed" randomly which indicates to me the issue has not been resolved.
