On 1.2.2013 we paid our last debit order to ADT for February 2013. On 15/2/2013 we made a lump sum payment
for period 1.3.2013 - 28.2.2014. Since December 2013 we have received an erroneous invoice on 1.12.2013
DEC2013STO15234 for R 7103.78. As we are in credit until 28.2.2014 (prepaid), this invoice must be cancelled
and a new one issued on 1 March 2014. We have contacted your call centre in December 2013, they admitted their mistake but have done nothing to rectify the problem. We have contacted our local ADT community development manager who has referred to people in the accounts department. Still no action has been taken
to rectify the situation. Please assist.
