Blue label connect are ******

I’m very upset with this company. They called me to sell me a contract phone and when they delivered it I refused to take it because it was not the phone we agreed upon, so I cancelled the contract with them, last night they debited my account. The amount of R329. They are ******. Please help me cancel, report anything. They have no business deducting any amount on my account. They should delete all my personal details on their system while at it.
