Osl wireless

Horrible company to deal with. They sell post paid phones at Walmart. Went to the Poland Walmart, was browsing phones ,looking for an upgrade. A girl named Betty started talking to me, she's an osl employee. She talked me into changing providers. Do not trust this woman, she did nothing but lie to me. Now I have a mess. T-mobile let me return the phone, but I list my number, now I'm still getting billed for a phone I don't own. Osl district manager will not return my calls , can't contact anyone at Osl. Guess I'm on my own straightening out this mess. . Don't trust Betty from Osl at Walmart, you will be in the same mess. They are not worth a star ,but you have to leave one. That's being too nice to Osl and Betty.
