Poor reception despite 4G LTE shown on coverage map


    My husband and I get consistently poor reception at 18109 33rd Ave W, Lynnwood, WA (around the Costco and Alderwood Mall). The coverage shows excellent coverage but our phones are literally unusable. Considering that TMobile's headquarters are located in the Seattle Metro Area, the reception we get in certain areas is unacceptable. We both have iPhone X and our difficulties are both indoors and outdoors. How can this matter be reported? TMobile chat seems pretty unresponsive.
