Complaint

In 2019 I took a contrat for 20 day and 20 night data for R150. The debit order went off my account for R205. I immediately called to cancel they told me i cannot as this was a 24 month contract. I informed them that I mislead. But then i decided to wait the 24 month then cancel it. I called 3 times to cancel the contrat but on every occassion. I was told they cannot cancel my contract because they can't access my account. "We can see you statement but cannot cancel the contract" said kirklynn Wilfred, one of the supervisors. I waited for 2 years to cancel this contract now the tell me they can. Please help me sort this out. Vodacom cannot lock people into contacts by misleading them.
