WORST INTERNET PROVIDER TO DEAL WITH EVER!!!

So I did not pay on month of my MTN contract. So the next month came and i owed R700 to them fine and well, i got some cash later on in the month and i paid them via the my MTN App, They then went ahead and debited R300 on the 25th again which i already paid for so i disputed the R300 because i already paid them. On the 3rd of February i received an SMS saying they are going to suspend my account due to non payment and that i owe them R723.61 bull **** . So i advised everyone please dont ever ever take a contract with MTN with company ever to deal with, also when i call the customer service line they talk in xhosa to their friends in the background and laugh. Please take my advice, save your time & money and dont do business with MTN TRUST ME!!!!!
