*****, taking advantage and lies, dishonering the contracts

I took a vodacom data contract, sim card only in January and canceled within 7 days due to bad connection. Cancelation went through and approved and the lady said she does not give out reference number however an email containing invoices was sent as proof of cancelation.

This month Vodacom debited its premiums even though I canceled the contract. Total dishonesty and ***** and I have not used the sim card at all.
