MTN HAS BLOCKED MY PHONE FOR THE 4MONTH IN A ROW

I do not understand how a service provider can keep treating customers like dirt.<br> <br> I have been a victim of MTN blocking my phone for payments that are due every month. In November i left the country and I went to Namibia . I had activated international roaming but most of the time the phone was off. I wasn't even using a smart phone. To my surprise i got a bill of 1050 roaming charges. I reported this last year and now that has caused the account to go into arrears because my bill closed in December and i had 3500 to pay(1050 roaming charges and 1500 outstanding bill). I paid 1500 and 1050 was outstanding.<br> <br> In January all my lines got blocked i asked why they said the billing amount i need to pay i cant pay for something that i didn't use??<br> <br> What is wrong with these people. they cant even justify who I called for the R1000 roaming charges.<br> <br> I have been treated unfairly by MTN and I really will not take any further contracts in future. I cant get calls or sms or make calls. Please can someone fix this so i can pay what is due in terms of my month and month bill. <br> <br> The other thing is one of my contracts is finish but they don't want to discontinue it.<br> PLEASE RECONNECT MY LINES ASAP
