No service and no willingness to assist with their errors

I would like to give -10 if possible.

I have been sitting on the phone for 3 hours today and no one is able or willing to help!

Vodacom made an error on my account end of 2024 to beginning of 2025 where they did not change my debit order date despite multiple requests.

Now that I am trying to purchase a house this is showing as a late repayment history and preventing bond approval.

I spoke to agents who confirmed that they see the error but no one is able to provide me with a error corrections letter to provide to the credit bureau for removal of the flags.

They said they do not know what that is. I sent a template to their email to get it on a letterhead but no response and no one can escalate it.

My offer on this house expires on Monday and no one cares. When my contracts lapse with them I will be leaving!
