Today, An agent from Telecom came to my apartment and shared that I must  switch from Vodafone to Telekom DSL. I filled the form and he told me that an Email will be sent to me and one of his team members will contact me for the exchange details, which should be next year, but I got no email or phone call, and also he didn't explained that this is not a must, so I want to cancel this request and make sure that your representative was legitimate
