Unresolved query

I have been calling FNB several times with no luck of getting assistance. I requested them to cancel the funeral plan because I was not interested I was only interested on life cover. They send me an email asking me if I am happy with funeral cove and I did say no. I even send emails but they do not reply. I went to their Boulders Mall branch in midrand but the only thing I was told they say no one will be able to assist me in the branch i have to call their funeral policy department. I have to wait on the que waiting to make phone call but there is no que to talk to consultant face to face and customers are not allowed to talk to them regarding funeral policy cancellation and is surprising because is FNB product but you can only be assisted through phone call. I went out of FNB without help. Today i went to them still tge same thing i had to make call. I stayed on the line and they dont answer again I walk out of the branch without assistance. Now my problem is I have already switched my salary to their bank starting from this month. They have already attempt to debit the funeral plan and the life cover off wich i have sent them emails to cancel within a week from the day that I apply for it. Now there are unnecessary charges that they are expecting to deduct from my money and is not my fault. Debit order shows that it will go off also. And I can not be able to change the banking details and remove FNB with my employer at this time of the month is late.
