Useless Service

I am really disappointed with Telkom. I have been trying to change my fathers account so that he gets a pensioners discount. He is 84 and has dementia. I also want to add the VAS Block Call service. I have been into the store and they say i need to call. I have been trying to phone for 2 days now. Still nobody can assist as they say they need to speak to my father . I mean really do they not get that he has dementia!!!! Nobody has been able to help me and i am very frustrated!.
