Telkom App - Abysmal service.

Have been waiting since January for a response to my request to change bank details. After several follow ups I was phoned, however I was not available and the rep said he would phone back later. 3 weeks and another follow up and still no response. Although the app is a secure one, you need to manually enter every single detail again for each follow up. Surely you would expect them to use available technology to pre populate your details. Very disappointed
