Charged additional data usage

For the last two months, the data bundles received monthly and additionally purchased have been used up twice as fast. This has never happened in the last 2 years of being with Telkom. We had requested the data usage reports and noted several discrepancies totalling up to Terabytes of data used. Large amounts of data would go off with a start time of 00:00 and end at 00:00. We were in contact with a Telkom employee questioning the data usage and have not received any feedback since 11 April 2020. This lead to being forced to buy a 80GB/80GB once off bundle to have internet again. The additional data bundle purchased, along with the standard 100GB/100GB monthly bundle received on 11 May 2020 had now been communicated as depleted as of 22 May at 7:10pm. The responses to our issues have not been provided with an definite reasoning, especially with the poor signal which cannot account for the amount of data that was supposedly recorded.
