Dissatisfaction of service - drafting of will

1 star is even too much! I have been sending numerous emails and follow-ups to the three consultants responsible for drafting my will, but after 5 months, it still hasn't been finalised. Meanwhile, the debit orders have been going off since May. Yesterday, I mentioned that I would escalate this matter, but there are no clear contact details for escalation. This has been the worst service experience I've encountered, especially from a company that is meant to focus on legacy planning. Could someone please reach out to me? I'm completely frustrated at this point.
