Goes in my account without my consent.

clientele goes in my account and debit and debit the why they feel like we agreed that they should collect on the 1st of every month. Yet without my consent they collect on the 15nd and the 23rd of FeB without calling me to make any arrangements or let me know. I get paid fortnight and the second fortnight wich is the month end is very important for me. They can call to make arrangements in order for me to know

I find this very alarming and inconsiderate.
