Gave the wrong advise...

I have been trying to get Telkom to call me since June....

They upgraded me over the phone and they didn't tell me there is a cost involved. Someone called me and said it was the store's fault for my LTE and I went there and they referred me back to the complaints department

I have FB messaging people and nobody ever calls back. They just say I owe the money. I asked for a copy of the call or for someone to listen to the call to advise if I was advised correctly.

This is terrible service...I emailed ********** twice and no response.

What more can I do?
