T-Mobile and assurion Fraud/ scam

I was almost scammed out of a replacement phone back in Aug. for my son's IPhone had to fight for 2 weeks was told someone else was using his broken phone. No one ever explained that mess to me but finally was able to get it replaced. Fast forward to now and I am going through it again. My other sons phone this time him and I upgraded to IPhones little over a year ago. His phone stopped working overnight I called assurion filed a claim was told I would get a text message in a a or two after the claim was reviewed so I could pay the deductible and replace the phone. 3 days later I called was told that my claim was denied because he didn't have insurance on the phone. Since then every time I call or my husband calls we are lied to told different things no one can answer simple questions such as how was I able to file a claim in the first place if the phone wasn't insured? Why are you putting me through this again like you did back in Aug. it's been nothing but BS. Then my husband was scammed by an after hours customer service person who convinced him that he had to add insurance to the already insured phone and then he could get it replaced only to be patched through to assurion who told him he had to now wait a month. You could hear other people in the background of his phone call giggling about us being upset when he asked to speak with a manager he was put on the phone with a man who had a thick accent and was rude. Disgusting behavior by customer care on both ends and still no resolution to my complaint or help understanding why I was able to file the claim. I know why I was able to file the claim because the phone had coverage originally someone needs to fix this but honestly I'm looking into switching providers and taking my complaints to the better business bureau because I've been lied to and fraudulent activity has occurred here. I could buy a new phone but it's the principle at this point. I guess this is what T-Mobile does doesn't value customers must not care about keeping them. I think I may post my experience on social media sights next to see who else has been through this surly I'm not the only one and this isn't the first time that they did something shady like this to me.
