Bad service overall

Since being force onto Autopage (from Nashua mobile) I had nothing but bad service. they don't send statements even though I phone more that once and even went to one of their outlets. after not receiving my bill again end of February I phone them( 4 March) again to send me the bill. the statement they send was for(total amount due) R1660.75 I paid R1800.00. today I get a SMS saying that to avoid being cut off I need to pay R583.74. what happen since the 4th. when I spoke to Auotpage I asked to escalate my problem and I was told someone would phone me before the end of the day. it's been a long day at Autopage because I still have not received that phone call. I also have an amount outstanding since December for R468.33 but nobody can tell me what it is for. As i'm typing this report i'm holding on for Autopage - its been almost 40 minutes and then I got cut off. the worst is that they do have all your details and they don't even bother to phone you back.
