I have complained to xbtec (and some other third party people who look after their services) about sending me unsolicited email.
I have never delt with them in the past and have no relationship with them in the past. I see it as spam (even if they did buy (or not) from blackarrow)

I have also asked for Proof that they have bought the customer database from blackarrow. There are only 2 choices..

1) I can go after blackarrow for selling my details when they say they won't.
2) XBtec are lying that they bought it from blackarrow

Blackarrow: did you sell it to xbtec?
XBTec: did you buy it from blackarrow?
