Contract expired and Claim that I owe R2000

I inherited this *********** company from Nashua Mobile as they closed shop.<br> <br> Dec 2014, my account was never debited as that is when the move happened, called them to find out what happened and they said they will rectify the matter, end of Jan my normal installment R800 for 2 lines was debited, inquired about the Dec payment they said account up to date.<br> <br> Mid Feb, both lines were blocked claiming that I owed over R1000, requested for statement and they said that it was for Dec as the limit aws exceeded. How can that be as we had the limit with Nashua and that never happened, we always had excess data, airtime and sms per month with Nashua Mobile, now with Altech we are exceeding? Interesting...<br> <br> End Feb Normal Installments were debited, March and april normal instalments were transfared, now juts recieved as very intresting document titled final demand on the 25th April for R2000,<br> <br> My contract expired this month, last month end and I still have not used any data, air timr as well as sms for the last 2 months.<br> <br> What a *******.<br> <br> Waiting to here what they will say and will forward this matter to ICASA as well as the civil court.<br> <br> Tired of talking to robotized consultants.
