what about next month when its still not fixed?

"Hi there, I am just following up with you on your service call and internet issues. We've checked with the local field technician supervisors to get clarification on what the area issue was that the tech was referring to. The fiber lines in your area are in need of upgrading and that is currently being planned by our maintenance crews although I can't provide any ETA for completion for this right now unfortunately. We appreciate your patience and understand that you have not been receiving the full service you have been paying for. In appreciation of your patience we have applied a one-month credit for your internet, you'll see this on your next invoice." anyone had a similar problem got a time frame i could expect? 1month 3? 6?
