Over Charging

October 2016 I agreed to a special offer that includes a mobile WiFi router with a DATA sim card with 1 GB data each month. A second sim card with 75 min. airtime, 75 sms and 500 MB data. for R138 per month. When received the package I discovered the second sim card only have 75 MB of data and NOT 500 MB as I were told. Numerous calls later and I could not resolve the issue. Then the next problem arise. Debit order was for more than the agreed amount. Again after some calls this was not resolved. It seems that once Telkom can deduct money there is no way to rectify errors. This reflect very bad on Telkom's ability to do strait forward honest busyness. The way my queries were handled I can not but regard Telkom as blatant and outright *****. After numerous requests to receive billing information I still to date have not received any. And like this month again the deduction is more than R200 over the agreed price of R138. I need someone from Telkom to assist me to rectify this issue that is nou going for 12 months. This is just way beyond ridiculous!!!
