Ive had the same thing,even after asking not to be called,still got msm offering to transfer me to MORE THAN for home insurance,i said no instantly cos i hate more than and their terms and conditions for car insurance so im hardly gonna be intrested in their home products.
The problem also is anyone who asks to be called ,can expect calls from associate companys(not sure about msm) after normal reasonable office hours,i recieved a call at 8.45pm.
The company i work for has a policy not to cold call or make solicited calls after 8pm as those hours after are deemed as unsociable,its a shame other dont have the same ethos.
