Bad service

We have two TELKOM business lines. The one line ***) is out of order for the past 3 weeks. The other line ***) previously with TELKOM and changed to Neotel a few years ago, because of bad service by Telkom. Beginning of May 2019 we went to Telkom, Menlyn to change it back to Telkom. It is now 6 months after several visits to Telkom, Menlyn and we still are without a line. Telkom send us the new phone about two weeks ago, but it is still not connected. In the meantime we getting monthly an account for a line which is still not working since we asked them to transfer it. During my previous visit to Menlyn, they said they will correct the account and they can see on the system that there was no service. Instead of correcting it, the account is adding up every month. On my visit today to Telkom, Menlyn I was informed that they are off line. Something, which did not surprise me.
