I rang slingshot and inquired about being put on ADSL2+.
I was told that it could not be done as I am on the all you can eat plan, as this is an 'ADSL1' plan.
I then linked the man i was talking to, to the url: http://help.slingshot.co.nz/app/answers/detail/a_id/1614/kw/adsl2/r_id/102266 Where it states that all FS/FS plans are optimised for ADSL2+. He threw me some stupid reasons why i couldnt be put on it after this and danced around the subject, he would not allow me to speak to someone else with possibly more knowledge or information on the matter and when i asked how i could go about getting ADSL2+ he said that i should move to Telecom, then in his arrogance hung up on me. This was first off terrible service and also did not satisfy me with a direct answer to my inquiry.
