Good afternoon, to whom it may concern. Please review my account and see how many years I have trusted Tmobile. I am sad to say that your coverage has become extremely poor over the past months in the Polk County area. I currently live in Winter Haven, but all 4 lines in my account expend the majority of the time among different area or cities within Polk County, Florida such as Haines City, Lake Alfred, and Lakeland. Our devices are not crashing they operate well, but the cellular data service and speed is very poor. Please follow up to this matter. We are not interested in new devices. We are more interested in quality service. Thank you. Please reply.
