Regret moving my RA to Sygnia - Debit order not gone through since April 2021 even after follow - ups

I transferred my RA from Old mutual to Sygnia in April 2021 paid penalty fees and all as I thought it was the best move. I am now having doubts about my decision because I have not been getting the best service from sygnia. I have been struggling to get something as simple as getting debit orders to go through since April 2021. Their debit order dates are only the 1st and/or 15th of each month and cannot accommodate any date. I have been making follow-ups on top of follow-ups since April and the debit order has not gone through. I am not happy with their service at all. I called them today and only to be told that they can't see the confirmation they have sent through on the 23rd of June 2021 which is even more upsetting
