Debit orders do not go off as they say

I app**** for a new contract and received my phone on 9 April. The consultant told me that the first debit order will go off within 48 hours, where after my normal debit orders (on my request) will go off the 1st of each month. Neither has gone off yet. Now I sit in a situation where I will probably be debited for two months in one month. It is ridiculous. I expected much better customer service from such a "respectable" company.
