Replying to Cast Touring

So I called them last weekend, left a voice mail, and emailed them about getting a boot conversion done, and I haven't heard back yet. Do they normally take a long time to respond or what? Has anyone else used their services before?

On another note, a friend of mine strongly suggested not getting the boot sole conversion done through Cast and just buying boots that are certified for tech pin bindings, so I'll probably do that once I have the money.
