Worst isp, stay away! They change your service package without your approval!

My package has been changed twice without my consent the past two months! Firstly I have downgraded to a 25/25mb line and then after a month it was changed without any consent to a 50/50mb line and now its changed to a 100/100mb line and my speed is still 50/50mb! I expect a refund of the package as I did not aprove change of service! I want my package to the intitial 25/25mb and not waiting a month to change as it not my fault! Surely it does not take 4 day's to respond to my ticket online! (S***) I don't care if Balwin fibre has agreements with you, it's within the company's best interest to notify the user and give him options to change the service or even cancel.
