vodacom stoled my money

On 9 February 2015 I found out that Vodacom did not stop my account when I phoned to stop it but continued to debit my account every month. Due to the postal strike I did not receive my bankstatements. I phoned and had to talk to several people before anyone could help me. The man told me I had to make an affidavit stating what happened and fax that with a cpoy of my ID signed 3 times to the legal department wchich I did on the 11 of February. I heard nothing and phoned again on 20 February. I had to phone twice and talked to a lot of people before I talked to Brilliant. He said when I phoned to stop the contract on the 7 April 2014 and talked to Koko she stopped the contract but made an error and did not stop it in 2014 but 2015. He said she made a mistake but he would stop it immediately which he did. He would follow up immediately that I could receive all my monies back which was wrongly taken from me,<br> . He said that I would be called back within 3 to 7 working days. which did not happen. I called again on 4 March and talked to Tumi. He said nothing was done yet but he would follow it up and I would be called in 24 hours. which of course did not happen. Please help me.
