BAD SERVICE

I am an all time Vodacom customer with a contract. My phone was lost and i blacklisted it in April then the phone was recovered then i followed the correct procedure of unblacklisting it . The vodashop manager at the Kempton park store told me it should be ok within 3-4 days but with no success I took it to the boulders vodashop which was unblocked and worked for around 3weeks (that was in June) or so and then the error mm#6 reappeared then i was told to go to vodaworld. i went to vodaworld (monday 20th july) and a consultant checked the phone and later emailed me to reboot the phone, which i did but the phone did not work. Still am stuck with a phone not working and no 1 willing to follow up. I emailed the consultant 4 days ago telling her tha the phone is not working and she did not get back to me. At end of the month money will be deducted from my account even though i a not using the phone. i am so disappointed and tired of being sent up and down to find a solution with no luck.
