Outage credit from hurricane beryl

I too am trying to find out about credit to my account during Hurricane Beryl. No electricity, no internet and no available hotspots forced us to use cellular data and exceed our limits. After power was restored I called customer service and was told an adjustment would be made and I would not have to pay for the excess data. Now, a month later after paying to excess charges, I am being told I will not be issued a full refund and I should have changed my data plan to unlimited to avoid the overages. I suppose if I had electricity, internet service or hotspots available I might have thought to do this while cleaning up hurricane debris. However, I did not and am now stuck with an outrageous bill. Moving forward in a hurricane prone area I can either tell my elderly mother and Downs Syndrome sister not to use their phones during a state of emergency or I can take my services elsewhere. I learned today that AT&T and Verizon waived all overages to their customers impacted by the storm. Xfinity, do better!!
