False sale assistance and no after sales.

The worst experience I have had with Vodacom taking out a wifi contract with Router. I was billed for a month without being able to use it once, spending time at the store, then on the phone. They kept on telling me that the services are not active but still billing me R588 for a month. Only when I returned the device to Vodacom they said but they need to remove the pin which they were supposed to do the first time I took out the contract. I was promised that we can change the router's password as that was a main condition prior to taking the contract and the router. Only then to advise me you can not change the password. I expect Vodacom who has been my service provider for 21 years to take back their modem, cancel the contract and refund me for a service I was never able to receive.
