Unsuspend my account asap I do now have arrears!!!

So I had financial crisis and I disputed a debit order which has since been paid with arrears but cellc suspended my account I0312I0312 .I still am not able to use my cellc number.I work for a big service provider like cellc and as an administrator I have never seen an account suspended for 1 month arrears.pls rectify this as its a first and have been with cellc for many years for them to treat me like this.My account is up to date but I can't use service how is that far .1 month arrears don't constitute a suspension and ridiculous.Again I received message saying my contract has extended to Feb ?how when this account is up to date. If this is the way you treat long time customers you will loose them take it from me who resolves customer queries daily.This is jst unacceptable. My account should be sorted before end of business today or I will escalate further.I have never heard in my years in customer service an account suspended due to 1 debit unpaid and which has since been paid via your debit system. Disappointed😞
