Ignition *********** group *****ing money

Ignition group contacted me to do an MTN upgrade. EIGHT hours of phone calls back and forth and my 3 numbers are upgraded and a new debit order signed. Nov payment goes off as planned. December amount has changed and then my 3 lines are suspended and I am told I owe R2500 and in fact only one number was upgraded!!! I have to pay the R2500 or my numbers cannot be unblocked. This is YOUR mismanagement and I expect to be refunded for YOUR disaster
