Issues getting invoice

<p>I just got my phone line installed after a few headaches last month. Afterwards I downloaded the telkom app to track my billing as I received no invoices about anything. After a while I see my bill is sitting at R1000 which seems high for just a voice line. I decided to call telkom to see what the issue is but they said they can't view my invoices and only when it's available can they explain the high cost. So I decided to wait for my invoice. According to the app the payment is due on the 30th and I've still received no invoice. It's extremely frustrating because I have no idea why the bill is so high and even worse is I have no invoice so I can't pay it off. I tried phoning several times and the responses have been completely useless, I just fear they will cut my line which is frustrating because I can pay it. </p>
