Let me first say I am so glad to have found your site! Now I know I am not the only person dealing with this "ZPDI" phone scam! This absolutely outrages me! This is what happened: In December 2000, I received my long distance phone bill from Sprint. It was much higher than usual so I looked at it in detail. I was absolutely shocked when I saw a collect call from Tijuana, Mexico! I immediately contacted Sprint to dispute the call. They informed me there was nothing they could do and that I needed to contact the company who handled the call, ZPDI.
I contacted this company and filed a complaint. I also informed them that, IN NO WAY was I going to pay this fraudulent charge, in that I did not accept any such collect call! They told me that they would put it in "dispute" and would investigate it. Again, I told them they could "investigate all they want, but that I was not paying this fraudulent bill!" I never received any response back from ZPDI and each month since I have been harrassed by Sprint for this charge!
I have written letters to both Sprint and ZPDI stating I am not paying this bill. But, here again, at the end of March, nearly five months after the initial dispute, I am sending a final written response to Sprint and ZPDI stating that I am not paying this fraudulent charge. I am most disappointed in Sprint because obviously, they are aware that this is an ongoing problem with this company! They should sever any kind of relationship with this company because failure to do so will only result in lost service to them!
