In correctly billing

<p>I have smart XS with Vodacom contract last month I reached my mandatory limit of R3000 which the person who opened the contract did not even explain to me.I was told the contract is an open line later when we went back 10days later and told we can't change until 3months. Last month we reduce our limit to 1500 and then within 7days in May I had reached 100% of my 1500 limit and the phone was soft locked. </p> <p> </p> <p>This is month I get a bill saying I owe R4000+ ? How? Because the phone reached its limit and was soft locked. Why is Vodacom over charging afta I payed. 3000 for April. And when you request. Detailed statement from their Customer care line they have excuses about the system being off or down ! I want a detailed summary of all the calls and data usage before. Making an payment. Instead of debuting on the 28 they also debit 5days later who is going to billed for extra charges/ arrears for them not debting on time? My *** urgently call me because now they making threats of taking the phone.</p>
