Bad service received from VodacomSA

I have been trying to cancel my contract with #VodacomSA due to wrong product delivered to me. The product was collected 14 days prior to the 14days given for cancellation, monthly instalments had been deducted from my account for something that I do not take responsibility anymore. I have tried to contact the #VodacomSA customer service to make follow up regarding my cancellation and I haven’t been helped to their best ability. #VodacomSA
