WiFi not connected since installation

I am not getting any assistance from zoom, they are cutting my calls Whatsup. I bought their service through webafrica after connecting the router webafrica discovered that the problem is with zoom fibre.

I went to their branch in Vredenburg they register the case and agent told me that they only depend on their head office jhb. Your ticket reference is . ZF000C6HN

I’m struggling as my kids are doing online I need them to fix this
