Account /billing - frustrated with Telkom

I am so frustrated with the service from Telkom. Since 2016 I have been communicating with so many different people to resolve a dispute. Eventually a back office consultant was assisting and then vanished without resolving the issue. I phone the number and no service, I email this lady daily and no reply. What do agents do at Telkom if they cannot assist customers? The account was handed over to the attorneys, and I contacted them and explained the situation with Telkom, he then advised days later that it has been handed back to Telkom. Please I just need to close this dispute and be done! Now we not only have unnecessary fees from Telkom but more fees on top of that and layers fees? Really??? I have tried to work with you to resolve this and all you can do is send updated invoices!!
