Bad Service!

I app**** for a cellphone contract in the beginning of May I eventually after fighting about sim numbers got my contact around the 20th of May. Now on Friday I get an sms saying my account has been suspended due to none payment. How is that possible when Autopage were to debit my account! So I went into the Ballito branch to query it. To discover they have set the debit for the 15th not the 1st as I requested. They then assured me this would be changed to the first but I was still to pay the now owing R490.00. I emailed Autopage on Saturday querying this as I do not want to pay this and then they debit my account. I have just received via email that my email query logged on Saturday has been closed. How? How the hell is it closed when no-one has even bothered to contact me. As now my phone is unusable!!! So frustrating!
