3rd party sold incorrect product and no response again

A 3rd party sold me the incorrect contract and sent me the home device incorrectly. I have been on numerous calls to Vodacom everyone telling me to wait for them to fetch the home device before they can reinstate the old contract ,as they confirmed that it was an error on their side.. i have had no response again and no courier picking up the device.. its been 50 days with the incorrect contract and i need to use my data 😒
