Could the cellc consultant please contact me or send me your correct email address in order for this nonsense issue to resolved. Following my initial review, Cellc media consultant contacted me in attempt to resolve the issue. The issue as straight forward as it is "incorrect billing post cancellation of contracts that were paid in full " he requested information wrt proof of payment and provided me with ane email address that has been returned to me with error email address.
