Enough is enough Telkom

I've been trying to contact Telkom to transfer my line to new premises from early January 2019. However I'm told constantly to contact their sales department, no one ever answers their phones. I've gone into 4 different branches for help were I'm told I should contact the sales department telephonically or email them. I've done all that to no avail. Today I go into the Telkom at the Grove Mall . There the consultant tried her utmost to help however no one at the sales department answered their phones. Finally she called another department because I'm at my wit's end & decided to cancel. Here I was told I must pay for services not rendered first, there after pay cancellation fees. Later this afternoon at 14:40 someone phones me, without give me proper details starts a conversation about telkom. When asked who she is she gives me attitude and hangs up on me.
