Brand new phone broken - bad service

We upgraded in January 2015 and took out a new more expensive contract to cover us on the data bundles. The phone was a CAT BQ 150. Within 10 days the touchscreen froze and the phone was sent back. 2 weeks later we received the phone but when we were in the vodacom shop the people assisting us there could not get the sim card into the phone as it was broken. Now 3 weeks later we still have NO phone. We are paying for a contract and phone for the past 3 months that we do not have. I am now sick and tired of the **** service we receive from Vodacom. I DO NOT want a CAT phone EVER!!!!! I am so dissapointed in the BAD sevice we have received.
