Poor poor service

I’m now out of words random debit orders are just going off , when a complaint is raised I’m being told that they will get back to me with feedback and and they will send someone to check but no one comes . I’ve been calling the call centre to date when you call the consultants and very rude and the always drop the phone or just mute on you . I think it’s high time I include my lawyer because my ITC status is being ruined because of all this
