The battery cover from my son's Omnipod PDM (like a little plastic battery cover on a remote control) fell off and disappeared. I called today to get it replaced and was told that they cannot replace only the battery cover. They said we will have to replace the entire PDM and that since this is not covered under the warranty, it will cost us $500. That is one expensive little piece of plastic! I asked for a manager and there wasn't one available, but they are supposed to call me tomorrow. Has anyone ever had a problem like this or had one replaced? I cannot believe how incredibly stupid this is!
