Incorrect Product Billing

Due to my past experience of bad customer service at Telkom I didn't even waste my energy on contacting them cause I'm not even clear what customer service dpt to contact for this query. They have a Mo' Black Friday data special of R50 for 5G Day' 100MB Social' 5G night' for 14 days. Bought the data and it says it will last 7 days not 14 days as advertised. As if that's not bad enough for 2 days Saturday & Sunday I did not have internet along with other users In Parys whereas other Telkom users had Network. I had R51 of airtime during that fiasco and 2 minutes later I had R48 airtime just for rebooting my phone. I put up with nonsense at Telkom in the name of cheaper rates.
