Migration Nightmare!

We have not had data since migration from ADSL to Fixed Wireless Broadband which took place 22 August 2019. I dont even know how this package we are on was selected because the account holder was never informed. We only found after calling a thousand times to have our data allocated that we are now on Fixed Wireless Broadband. The account holder (my mother) received a statement last week and is being billed for FLLA Fast and SoftCap 100GB for Aug-Sep and Sep-Oct but we were never allocated that data. We have a bunch of reference numbers from faults logged with regards to data allocation. We call and get sent around from one department to the next. Now we are told there is a Change Part/Replace Offer on the account. How does the Statement get updated to reflect that no data was received and only charge for voice service until the data issue is resolved? Why should my mother pay R500 of her hard earned money for data that we never received?! If Telkom's technical department or IT is having whatever problem allocating data to us, then can they just cancel the contract we have with them and collect their devices and have us be done with Telkom. We are sick and tired of calling like we are the ones at fault. A whole three weeks of calling almost daily , sending emails and waiting yet the account holder is expected to pay. Get your ish together Telkom. Don't **** us off anymore than you already have and fix that statement and remove the data part on there ASSEBLIEF!!
