3 weeks later and no response from Autopage

I have logged a complaint on here on 18 March. Autopage responded with immediately to say they will get back to me, which they never did. My initial query dates back to 3 March and now it is 3 weeks later without Autopage giving me any response or explanation.<br> They know they will get their money at the end of March, as my phone is on contract, so they will not bother to sort out my query.<br> According to them my reference numbers for complaints logged have been resolved. Reference numbers 614867 and 600096. My Autopage contract is more than 15 years old and my monthly cell invoice has NEVER exceeded R600 per month in the past 15 years - how do they explain that I now suddenly have a cell phone bill of R2 200?<br> And they refuse to give me an explanation or assist me.
