Bad service👎

Good day I have been a cellc client for the past 7 yrs and all of sudden they are really making my financial life a mess.i am currently unemployed and I have notified them of this but they still continue debiting different amounts from my account that I did not agree on .they stopped sending me monthly data yet they still continue debiting 299 and 218 and this is leaving my account on a negative. The original amount that they must debit is 149. I did call to complain about this but nobody came back to me about the rectification.can cellc pls rectify this and put back all the charge fees that I was charged for there mistake
