Hello 

A lady visited us on 27/10/2023 claiming that she is from Telekom staff came into my house and said that Telekom is changing street internet wire to optic fiber and all vodafone customers will be moved to telekom. She asked my IBAN NUMBER and my wife gave and asked her to sign on IPAD. My wife signed doc stating "ihr auftrag für telefonie, internet und fernsehen über vertriebspartner" 

After, they have left, when I googled it I found that they are scammers providing false/misleading information are convincing  to sign the contract with Telekom. I wonder if I am scammed by them. I went to local store and  they told to mail widerruf@telekom.de and later I called on hotline and they are asking for customer number, which I don't have. 

I don't want to go ahead with this shift to Telekom and need to cancel if contract has already started.  Could someone help asap please. Thanks in advance!!
