Sage pastel doesn't want my money

I have been trying for 2 months to get a debit order re-instated, after Pastel never re-instated the debit order on my instruction in November 2021. My emails are never rep**** on, especially when I ask for feedback and acknowledgement. I have even gone through Facebook Messenger, but still nothing happened. I have 2 email addresses of direct contacts, who just ignore me. Never confirming what I ask for. How am I supposed to know if my debit order will now be going off in March? This is pathetic.
