Debi Check Mandate policy violation, dishonest business conduct and sales people and poor service

Took a contract with them. The sales person said that I will only be charged the subscription fee and no additional costs. The sales person lie, my account keeps being debited with 2 addition debit orders (never received the Debi check mandates, and yet my account keeps being debited) I called last week to have the subscriptions cancelled, got confirmation Sms for the cancellations but my account was still debited this morning. Called in, was told the matter will be escalated again, and the managers do not speak to clients on request.
