I did not have an issue with Telkom until I decided to change bank accounts and my debit switch was not done. Fair enough this is my fault. Apparently Standard Bank has charged Telkom R250 for every attempt to debit a closed account which I now owe. I have asked a Telkom agent at the Telkom Store in Lakeside mall for a full statement and they could not provide me with one. They could only show me a mini statement on their computer screen where I noticed that I am being billed more than was agreed. When I took the data contract in October 2017 I was advised and agreed to paying R149pm for 24 months. I see that I am now being billed R340. I've made 2 manual payments to get my account up to date however after having my banking details corrected I was debited around R800.00. I've emailed ********** on the 11-05-2019 requesting a full statement and have not received a reply yet. Can I please get assistance or can the contract please be cancelled.
