Horrible app service and customer relations......

Sprint.... doesnt work in blair at all and I called sprint to talk it over but the call got dropped.... at least a dozen times... hung up on twice..... even with att on the line on a 3 way call !!?.... cant say how pist I am !! I had even went into the sprint store and they couldnt do anything because I got the"deal to switch" online Sprint doesnt have my old phones anymore. Now phones dead its started talking to them at 11am its now 8:30 just finished a 1.5 hr hold time first I told the person dont put me on hold I explained everything to her told her I opologize if Im a little Angry but Ive been working on this since 11 this morning... asked her please call ahead and make sure hat someone will pick up when you transfer me..... 1hr later finally talked to the last person ..... she said why did they send you to me they are the ones that know about this Im so angry its not funny. They have my old iPhone 6s X 4 and I have the I phone 7 X 4 they want theres back but wont give mine back. They want over 600.00 keep the 7s. That they turned off!! Does anyone know what I could do or who I could talk too? Should I call the better business bureau? Oh wait they turned them off. Update three whole days no resolution and they want close to 1000.00
