Forced to take something not wanted

Hi I'm sure not everyone has the same experiences as I had. with this said please make sure not to allow any Rep to stop a call if he/she has not explained everything that you need. I however listen understand most. but when it came to the "T & C" the call suddenly is rushed. Maybe its to much to say so get it done, from the very first day I realized that the deal is not suited. I tried to get more info. well of-cause there were delays. So finally I'm able to talk with someone after 5 days and was told the sim is on its way. alas its too late the contract was approved. Now more than ever I do not want it even if it is the best.

If I cancel now I might or will be liable for costs that could have been avoided if I had keep calling and being delayed and than call again and wait. luckily I got all the emails reference logs.
