Premium increase with no notification

I do need to mention that the way home connect initiates its business practices its terrible. We consumers are basically told our monthly premium will increase at any point without any notification because market dictates. I have no problem with increases bearing in mind inflation however no person or company has any right to decide with no notification how much they will start to debit from your account. What I find interesting is when there is wifi outage due to maintenance or other issues they more than capable to send sms to let us know but they unable to apply the same principles to premium increase. Another point in normal business practise premiums generally increase annually why can they implement the same principle here.I have requested a call from cancelation and to this moment nothing.
