Безопасен ли smartfren.com?

the main website is okay, but the company's services are not completely satisfactory. for example, i) there is no early push notification to inform users that our internet package is about to end, ii) it doesn't inform users how much of our internet quota remains from the current month and if the remainder is carried over to the next month, iii) it automatically disconnects our subscribed internet package if we have not topped up, or if there is insufficient cash balance without informing us before the service is terminated, iii) the child website, https://my.smartfren.com is problematic. it doesn't feature the transaction history at all, even after we have topped up using our credit card. there is no billing history/record. the site is supposed to contain point reward system, but the site showed no information to how much points we have, and how much points we can use to be exchanged. the online chat support system never worked.
