Seems to be used for some telemarketing call center - this range of numbers 16893259xx (common feature, they use more numbers of the same range) is mostly reported with Pension review company, PPI. Just block it if not interested (I use the app from these pages, no problems). Folks did they call you with the same or something new? I really don't answer unknown numbers and don't want to call them back...
Caller claimed to be from an insurance company and was ringing about an accident I was supposed to have been involved in that was not my fault. Apparently my car had been damaged! When I said that there had been no accident and that as of minutes previous
