Why are you so dishonest?

I moved to a new house , and at the old address I had only a Telkom li ne that I needed for making calls -for internet -I have Telkom LTE that I’m very happy with -I then asked if Telkom can transfer my line to the house , the Telkom man phoned me and made an appointment to do so , all very professional , and on the day they were here to activate my line -my number changed , they went out to the box and when they came back I noticed this man was connecting a router to my line , I told him I only asked for the normal line to be transferred , I already had internet , he told me it is a ADSL line , and I can cancel it later , now why on earth must he activate something I did not ask for and then tell me I can cancel it later , he had no problem just ignoring what I was saying , and why do I now later have to proof that I did not use the ADSL -very disappointed -I’m already buying my data from Telkom every month -why must he now add this ????
