While abroad, I switched of the roamaing function and also the mobile data of my iphone. Nevertheless, I still got phone calls through my combox (without seen it because the phone was not ringing, nor messages was left). Anyway, because I never received/got the calls, the calls went diverted to my combox. Result: addtional costs, as Swisscom charged each time someone (or even telemarketing) did call my phone number. Anyone had this experience? Is anything I can do to prove Swisscom is acting incorrectly icharging us for such cost? I can't find any information on that, nothing mentioning the importance of blocking your combox if abroad to avoid additonal, unexpected costs.
