Dead zone near clifton commons, NJ 07014

I have complained to Tmobile that around 5/6 months ago that near Clifton Common, NJ 07014 area, there is a dead zone. It was great before that time, customer service had indicated that are working on cell tower so it will be fixed soon. Same condition after 6 months. Replaced sim card, bought 5g brand new phone and same issue.  All other people also indicated that Tmobile service in that part is really bad.  40.827, -74137 to be precious in geo-location.
