Closure of Bank Accounts

I want to close my FNB accounts. Have a cheque account, a savings account and a loan that has been payed of but still shows on my profile. This morning I got a call from FNb stating that my cheque account is closed and I will be transferred to a different dept for closure of the savings account. The lady on the line then informed me that they cannot access my details because my cheque account was closed first and that was the wrong way to do it and I must now go into a branch to have it closed. Problem is, it's first of all not my mistake and secondly I cannot go to a branch, I live quite a distance from the closest branch and do not have a car to get there. Is it possible to be assisted over the phone as I'm sure you have great systems that can be used to do the job.
