UNSATISFACTORY SERVICE

When I upgraded to a new phone, I asked to be on PAY AS YOU GO. I struggle since DESEMBER 2014 to get this problem sorted out. My new phone was on contract and not pay as you go as stipulated on my contract.<br> Since then they deduct money from my account after I have brought it to there attention that I am not on Pay as You Go. They deducted +- R900 the first time which they paid back. And then told me that everything is in<br> order and my phone is now on pay as u go. After that they deducted R800 and R1200 and still the account is running on Contract and this after I get messages that my airtime is finished. I buy airtime and still pay a huge account. We filed another complaint and Mr Christiaan promissed us that he will get back within 2 days like he promised in January and 2 days became 2 months and now again. My account is over R400 already and this guy is not keeping his promise. Mtn needs to pay back all the money they have deducted so far. I really need some help.<br>
