Telkom Migration to LTE a mess

I have a Telkom landline and ADSL wifi router with unlimited data. I have a month-to-month contract.A couple of weeks ago I received a wireless home phone out of the blue - no explanation as to why. It is a wireless FLLA phone. The same day my landline went dead, so I thought it was a replacement for my old home phone. On Monday, 6th July, my ADSL router stopped working. When I tried to report an online fault, there was no option for ADSL so I phoned 10210 who put me through to 10213. It transpires that the phone I received is part of a migration away from copper wire, but because I had an ADSL line, they should have sent me a LTE router, not the FLLA phone. They promised to resolve and said I should give it 48 hours. When I called today, they said they can see the problem on the system, but nobody has responded to it. Are they aware that it is lockdown? I am working from home and my daughter is writing varsity exams from home!!! How long must I wait??
