Bad service - charging me for something i did not use - money making scheme

Terrible Service!

I have a LTE router contract with Telkom which is capped (always has been). I then receive a bill this month for an extra charge of R500. My router has been off for the last couple of days in August. They tell me that i used extra data on the 28 September 2019 (Dont forget my router was off - not plugged in). They say i used and i must pay. Soo bad - cant believe i get charged for something i did not use and Telkom does not want to resolve this. I also did tell Telkom that my account must stay capped since the day i signed up with them. After a year - now they all of a sudden charging me extra. Can't trust them - such a money making scheme, its easy for them to ***** from their own clients. - i rate Telkom a 0 of out 10. Many other people constantly complain about Telkom. Don't do business with them.
