poor service

Cell c insurance service is just disgusting ,i took out insurance with Cell c in july they activated insurance on an old phone when i called them they told me they not going to debit my account as it was still pending and they were going to cancel it , this month they double debited me . when i called i was told to send an email to claims@deviceinsurance , ive done this and now im being asked for my subscriber agreement , which i also called the call center and spoke to LUYANDA MKHIZE and she told me she could not assist me with my contract , she then went on to say no manager is available to speak to me as they are all in a meeting , I would like this issue to be sorted out .i would like insurance to be activated on my current phone which im paying for . If i had a choice i would cancel this contract as cellc service is just disgusting . I need someone to call me and sort out this ASAP
