have downloaded your app and paid 1€ (the offer from your advertisement) to see what you can supply me with this n my English journey. I have found out that I do not need this level of language experience and have deleted the app.

Unfortunately You have made numerous attempts to issue a withdrawal from my appointed bank account. I have not agreed on this.

So would you be so kind to refer from this and withdraw from further attempts, otherwise I will be forced to block you and write about it in Google play etc. Apart from contacting my lawyer.

Please make sure you have dropped all of the previous invoices except for the one I have specifically agreed on - 1€. Any other are NOT accepted and therefore not acceptable. 
Best regards, 

Thank you very much in advance.
