deleted number

Hi, my number has been deleted a week ago and customer care advised that I should write an email to *** to say that I need my lines to be reopened as my debt review does not cover this Vodacom account. I do make payment via a debit order and my last payment for the outstanding amount went off on the 26 of February 2021 and was successful. I have sent through many mails to Vodacom and it's now more than a week later and nothing has been done, no response whatsoever. I cannot enquire about this number via call center anymore because it says it does not exist. Please help.
