Good idea to check that. First thing you need to know, providers in Israel (as in most places) bill as postpaid. When service is terminated they do not immediately charge you for the days of service until that day, rather, they wait till the end of your billing cycle and then prorate your bill and charge you accordingly. Secondly, with some companies, it could take up to two weeks until they actually cancel your line. Therefore, you may still see one or two charges after you requested/confirmed the cancellation. You should be keeping an eye on this and it's always worth confirming with your provider that services were indeed cancelled.
