Disgusted once again

So I have been paying for my account and last month I had paid double so therefore as a client I would assume that I would be in credit, so then today the 04.06.2022 I get a message to say that I am going to be deactivated because my debit order did not go through but I assumed I was in credit, what absolute nonsense is this for me as a paying client who is in credit be deactivated, I have had issues before where you had put me on the wrong service provider and now I am having to deal with this, maybe the ombudsmen would like to hear from me as I have gone that route before and won the case before.
