I recently purchased a new cell phone and changed my existing number. I immediately began getting phone calls from Allied Interstate.
I asked repeatedly why they were calling and how they had obtained my number. They refused to give me any information unless I first gave them my phone number. They would curse at me and hang up. I then began to ignore their calls thinking I would look them up online, file a complaint, and register my number on the do not call list.
The calls persisted in the meantime. I finally answered thinking this time the person on the other end might realize that there was some mistake, make a note of it in the computer, and then the phone calls would cease. The person was very rude and hung up on me three times. I finally got someone else who insisted that I knew the person they were trying to reach or was that person.
I spent the next half hour very childishly calling and annoying the staff from a different number. I would insist that they owed me money and that they pay or I would sue, I would order pizza, and just in general be a pest. A very rude pest. It didn't help but it was funny.
I don't know how to get rid of them but I will send them a cease and desist letter as someone advised on this site.
I don't owe these people any money and I had never heard of them until I looked them up online and saw the numerous complaints. Good luck to anyone suffering from this company.
