Lodging a formal complaint

Last week/ this weekend, I have had mantince unannounced do work and drop and mess up my internet, I have told reps this can't happen, I offard to pay more but no plans are better at stability. On September 1st I was notified of planned maintenance scheduled for 1:03 AM this is the 3rd time doing mantince in 7 days but this time i was notified.

However, service was cut early well on live chat with a agent/rep trying to find a soultion for my problem, without warning, disrupting ongoing work for the 3rd time in 7 days.

While trying to get support, I was transferred between four different agents. Instead of solutions, I was only offered bill credits. The issue I raised was not about money — it was about continuity of service during maintenance. I rely on stable connections for important projects, and unannounced outages cause significant disruption.

Most concerning, one representative dismissed my situation with “leaving the chat”  ending the conversation. That level of unprofessionalism is unacceptable. Following that, the system reported “no agents available” until 3 AM, leaving me with no support.

Key Issues:

Maintenance began earlier than the stated time.

No options were provided to maintain continuity during the outage.

Agents focused only on credits, not on solving the root problem.

Representative misconduct (“left chat”).

No live agents available until hours after the outage began.

Request:

I am asking for this incident to be reviewed formally. Customers should:

1. Receive accurate start times and advance notice of maintenance.

2. Be given continuity options (hotspot credits, phased maintenance, etc.) when possible.

3. Expect professional conduct from all representatives.

4. Have support available during outages, not after.

Tonight I am left with confusion and anger, my isp is no longer reliable my issues of stability are not important. But you still try to sell me a higher speed? I am very shocked and disappointed  in xfintey.
