I know this is an old thread but I have the same current frustration , want to buy a kemper remote because I couldn't afford one when I bought the unit
[ it was expensive enough as it is ! ]
No kemper store in Canada where I live, the U.S exchange is more money than buying it from the uk , so tried to buy it online from there
CC processing would not go through, emailing kemper sales seems every other message is ignored or not responded to and a few " we looked into the website and everything is ok "
everything is not ok , I called my CC company they saw no record of attempted transaction , tried it in real time while the CC company was on the phone and they still saw nothing and
saw no problems with the CC, Either way kemper didn't seem to care about making my sale or me buying a remote or actually helping me, happy simply to say , our website is ok
I could have bought a Helix for less!
