It seems that Handtec and Sellphone24 are the same company. I initially dealt with Handtec but ended up communicating with the Sellphone24 team. Same issue as everyone else is reporting, but I would like to add, if you find yourself having made the unfortunately choice of selling your phone with them, don’t accept their “stock” reduced offers. Demand they return the handset unless they Honor the quoted price. And next time, avoid!
