Nedbank Thrupps - Incompetence

We had a stockvel account with Nedbank, we closed the account. Not all the monies were paid over. on 8th February 2018 we went there to collect the monies, as usual they were issues they couldn't cash their own check. We suggested that they pay over the monies to my account since I am a nedbank client. we signed the EFT form etc, they said it will be available the following day. I called 2 working days after now they say they paid over the cheque into my account it will take about 10 working days to clear. Today its the 6th of March 18 working days I call the bank to follow up on the payment. The inquiries consultant just tells me she doesn't know why, the bank manager is not in, the other inquiries lady is on training. Nowadays I use Nedbank rosebank or Sandton I cant deal with nedbank thrupps anymore
