Unable to change banking details / *********** staff

I have been with telkom for many years and within the last year their customer service has dropped to zero. I have been trying to change my banking details with them so that they are paid since March 2020 and there has been no form of assistance. I was told that my banking details were changed and I needed to wait a month before it was updated. I agreed knowing I would be paying banking fees for just one month to allow telkom to their monthly payment. My husband advise me to keep the bank account open for one more month as telkom gave him the run around when he changed banks. Low and behold they deducted from the wrong account for another month. Contacted the store and I was told I needed to come in due to the need of biometrics to change my banking details. Everytime I go to the store they are offline. Staff have a simple reply, sorry we can't help u as we are offline. There is nothing we can do. There will be new staff tomorrow, so you have to come in then. This is most frustrating. No sense of customer service to Atleast say, pls leave your details and we will contact you as soon as we are up and running. I have closed my old account and. Now this is telkom problem. I refuse to continue paying bank fees just because telkom has *********** staff.
