Telkom LTE

Telkom LTE - I have a contract that was upgraded last year Nov from 80 Gig to 120 Gig. The 80 Gig was sufficient and the upgrade to 120 Gig obviously sounded like a good idea. I moved and had to start streaming my TV so increased usage was expected. Never thought TV will have such a huge impact. I had to purchase additional data during November and December to get through the month. I bought unlimited bundles, first for 30 days and then for 7 days. What upset me is the fact that when my normal data per contract was uploaded, the usage was immediately deducted from my contract data whilst there still was balances left over on the unlimited "cash" bundles I bought. I have logged call backs from Telkom but to date have not received a call back. Someone phoned me once, asked for my ID and dropped the call, never to phone back again. I feel that if i bought an package because i am out of bundle then the usage must ne taken off that bundle saving my contract value for the rest of the month. Still waiting for call back......Fibre here we come ....
