Feed back not given

I took insurance with cell c in November and I was told by a consultant that they will debit on December and they failed to do so then on January I went to inquire about it and I was told that my contract was not activated that is when I told them to close it they reply buy saying they said it is closed and I asked them if they won't debit it and they rep**** by saying they can't debit what is not activated. Now my account is debited twice and when I went to cell c northgate the team leader inquired and she said she will give me feedback on Monday even now she hasn't given me a feedback at all feel like they are making me fool while they take my money for something that was not activated and I am angry for not being taken seriously just because I was friendly to them and they think they can take an advantage of me this what I call bad service on a high note
