Useless service from vodacom

I purchased a brand BlackBerry 9720 in October 2014,around March 2015 the charging point stop working. I booked my phone in,hardly used to be fixed. I was given an old refurbished phone. Since then the refurbished phone has been booked in 3 times in the last year and and half for problems with the scroll as well as the charging point again, and 3 days later since it came back from repairs it keeps starting and freezing. Each time I booked the phone in at a Vodacom store in Lenasia I explained I do not want a refurbished phone. I was told to contact head office with regards to this. It is with great regret that i have to put thia on hellopeter as I have been a loyal customer to Vodacom for the past 6 years. Please contact me on ***. I also plan to put this in the newspaper as well as on Facebook.
