Service Suspended

I am originally a Nashua Mobile (Cell C) customer and was transferred over to Autopage. I was on debit order but this seemed to fall away on trfr. I have been battling since early December 2014 for Autopage to reinstate my debit order. Several phone calls over the months and several promises from Autopage that the debit order would be activated from the end of each of the months that I have been phoning - and still no monies taken off. An sms of demand was sent to me on 16 March 2015 stating that unless an amount of R366-50 was paid, my service would be suspended. This payment was authorised and debited on 17 March 2015. Today 26 March 2015, my service is suspended and I am told that an amount of R497-00 would be dbted on 31/3/15. as pymts from last week are still not credited ( 1 week later? ). And I was told I had not bothered to pay my account for 4 months - check my history and reference numbers since Dec 14. Maybe they need to check their phone recordings as well, of all the conversations. I am thinking of migrating when my contract expires next month. I am at my wits end. Please help!!!
