connection problem

Every day now. Every day my service goes. Ive spent HOURS on the phone with support to fix the issue only to have it start happening over and over. As an active market trader they have cost me thousands by blocking my access to the markets while I have open trades. I'm also told Every single time that " the problem is 100% fixed" . No, not it's not fixed. My recommendation to Tmobile ( a local company whom I've worked with in the past) is to stop spending all that time and  money relaunching  their apps every couple of years and focus on not screwing over so many of their customers all the time. I mean if it takes a year to upgrade one single cell tower then they need to look at better subcontractors to install the new gear. What I suspect is really happening is, in an attempt at improving their bittom line, they are cramming too many customers onto too little cell tower bandwidth. Leaving their customers and the customer facing employees out to dry. I'll bet you if you total up all the money I've lost trading with TMobiles unbelievably unstable connections it's pushing 10K by now. All because I can't execute a simple sell order. We'll as long as their quarterly numbers are up it's all for a good cause right? Who knows a good attorney? Seriously, if you do, just respond to this post and I'll reach back out to you.
