Called saying there from Brands By Choice (googled them website dodgy as) I called the number back and it says its Omnilead. First time said it was about a survey second time about a competition I had entered which I had not.
Have received persistent calls from this number at least twice daily over a period of days. My home phone is a call screen phone (available from Spark) which asks for identification before putting the call through to me. They do not identify themselves, So the call is not put through. I am sure this is a spam call.
