Disgruntled customer

I am very unhappy right now about my account, i have been paying my account via debit order and i noticed that my account was not debited this month and today i see a bill of 765 for 2 compacts and re connection fee that i know nothing about and if there was any issues with the debit order this month i needed to be notified about that not have my services disconnected. i need answers asap and this issue resolved. i have been paying 638 for the 2 compacts and i made changes upgrading one to DSTV extra and downgrading the other to family one of the changes i set to take effect on the 03/10/2015 and the other was set for the 25/09/2015...... i want this sorted by close of business today.
