NO RECORD OF OUTSTANDING FEES ON ACCOUNT AND EXCESSIVE CHARGES!

I have been assisted by a wonderful lady from Telkom, Really would like to give her an honest compliment and this is certainly not directed at her in any way. However I am honestly very very disappointed in how the accounts are run within Telkom. I have a R269.00 LTE package of which I have been having continual issues. However after the last contact from a lady from Hello Peter Department whom informed me I can take back the router and the contract will be cancelled without penalties. I continued to give Telkom the benefit of the doubt and continue to use the device and internet of which has been surprisingly good this last month - However Telkom attempted to Collect R740+- of which failed as there have only been enough to cover the R269.00 for the contract in my account of which point FNB charged me R110 unpaid fees. which hence makes the collection of the original value of Telkom R269.00 unaccessible. irrespective life goes on and now I have heard from the lady that helped me told me that this account is now in the thousands due to uncollected PENALTIES. Now my question is unless I received this little SMS when was someone going to notify me before over a R1000 was charged excess for R269.00?? Is this fair? THE Telkom PORTAL is a complete JOKE and relays ZERO information of this amount? Can someone please help me rectify this matter. I honestly am not going to use any Telkom products further going forward. Such lovely employees but terrible delivery.
