account still suspended

i am a very angry client at the moment. my altech autopage was suspended due to a returned debit order. i had made arrangments for my account to be double debited for the month of june. i have been calling the call centre since last week and everytime i speka to a consultant they reativate my line only to find out that its suspended again. i even called the naedo company to confirm if my payment has been receieved and i was told yes, i went to the branch yesterday to collect a bank statement from my bank as proof of payment, i spoke to 3 consultants today but no one seems to know what the problem is. i just want my line to reactivated. i need to use my phone urgently. i have a son who has chronic illness and phone needs to on 24/7... my upgrade is due in september i will not upgrade my contract. someone please come to my assistance or i am foced to take further action
