DEBIT ORDER SWITCHING - WHAT A NIGHTMARE!

I have app**** for debit order switching on the 26th of October 2017. I had contact with Nokuzola Msuthwana from FNB's admin offices in JHB from the 6th of November 2017. As to date, we have not heard a word from this admin. I have sent her an email on the 8th of December to follow up - no reply. I sent her an email AGAIN on the 5th of January 2018 and up until today, I still haven't received a response from her. On top of it all, we are paying DOUBLE banking rates, because all our debit orders are going off on our ABSA acc, which we need to keep open because FNB hasn't contacted us or kept to their word - Initially, FNB Vredenburg told us that debit order switching will take no longer than 3 weeks. We are currently at 11 weeks and still nothing. I'm extremely upset about this because we moved away from our previous bank due to bad customer service. Kindly let me know what is going on with our debit order switching as soon as possible or I will have to find a new bank.
