MTN ARE ******

i cancelled my contract when it expired i think in Feb and was told its cancelled. After 3 months i get an sms that im in arrears and i paid the amount. This morning i get an sms again that my servies will be suspended and reported to the credit bureau if I dont pay R62. I call the call centre and the rude lady tells me it wasnt cancelled it ws put on month to month. I am not even getting any invoices from MTN so Im thinking the contract is cancelled yet its not.
