Cellc Collections Depart

On numerous occassions I have called into the customer care centre to cancel monthly data bundle as I no longer required it. Account number *** The customer care consultant was never able to pick this up and advised to put me through to the retentions department. Everytime being cut off. I receivef an email fromcollections advising that payment needs to be made. I responded advising of the above I now received an email advising that if this account it not paid all my services will be suspended. I have been with cellc since the beginning and find their services very poor. Please can someone from collections call me urgently as I feel this is unacceptable.
