Roaming services

This is my second complaint on roaming services, it’s a nightmare when it comes to roaming a simple thing that I have to struggle to get right with vodacom. I left SA for America on the 9th of December 17 activated roamon then travelon via sms but was only get sms roaming. I later emailed customer care for them to activate both but they deactivated sms only to keep the calling activited . Now that I could call I called customer care for them to active both sms and calling . Now I have no service at all . I do know maybe I do not speak clear English and there seems to be a miss communication somewhere Lord knows . All I need is to be able to access my sms and calling services when am not in the country. Am super frustrated now ,am missing out on business calls and sms notifications from my bank . Honestly vodacom needs to sort this . I can not do without my phone.
