Last year a Telekom agent visited my apartment and said they are switching the internet connection to Telekom for the entire city and it's mandatory so i agreed and gave my details.

I have received an email with order confirmation and details for switching. 

However, the new contract made by him is higher priced for faster download speed then my current contract at Vodafone , I do not want to switch my cable internet service provider 

Please help me cancel this order or contract.

Best regards.
