Poor service or consideration for clients

Ive been having issues for a while . The download and upload is not what im paying for. After months of paying for a service Im not getting, they finally managed to get open serve to come out and find theres was an issue with the modem. It was replaced . Technician took forever to get it reconnected. Few day later Friday 28th I pay my bill only to discover that the wifi is out again. It all depends on who answers your call. The first consultant a few day early was wonderful but this time I get through the consultants that just follow a script. No one willing to escellate the issue to open serve. No team leader and manager that can assist. I mean imagine paying and discovering the service isn't working. Imaging paying for a certain speed and yet you haven't been getting that speed for months. An entire weekend without a service I jus paid for. Wow! Why do we have to resort to complaining at this level before anything is done. I hope and pray thisbis resolved ASAP or else Im cancelling.
