ZERO Inbound Land-Line Calls and Poor call centre service.

Good Day, I am EXTREMELY unhappy at the fact that for the last month and half i cannot receive Land-Line Calls, and sometimes cellular calls on my line. from the beginning of Lockdown the call goes straight to Engaged tone and i get 2 notifications that i missed a call from that number. Sometimes when i am on a call to a cell number, their last word will just echo 3 times and the call will cut and i will have to phone them back. I have not had this problem before in over 18 years of having this contract. I started phoning the Call centre from 1 May to try and resolve this issue and have yet to get a senior technician call me back (from their cell phone) and try and sort out the problem. Everytime I tell the call centre agent You cannot phone me from *** because I do not get the call at all. my reference number ticket was just closed and forgotten about! #*** #*** I am the idiot who has to keep calling in and try and explain my story 50 million times to different agents. To this date nobody senior has tried to fix this issue. Vodacom you have until tomorrow 21st May 9am to fix this or even just call me back or you can forget about taking your debit order until this issue is resolved!
