Lack of adequate service

I am extremely disappointed with the service this month. Firstly, my debit order went off at a later date than our agreement stated and what I find unprofessional is that I was not even informed. Secondly, my debit order has still not been allocated to my account. I tried calling yesterday and held on for sometime. I then sent a WhatsApp and was advised that I would get an email with feedback by COB yesterday (which was not true because I have received nothing). I sent an email today but also, no response. When will my debit order be allocated?? This really isn’t cool.
