MRP Mobile- rude call centre agents

MRP mobile telemarketers are rude and ***********. They contacted my husband regarding an sms they apparently sent to him, when i asked what the reason for the call was, the idiot says it is confidential and he doesnt know what the content of the sms was. This was clearly bull ****! I asked what they are wanting to sell they didnt want to tell me, all the person said was that it was related to an sms. They are phoning people who did not give consent and they cant even tell the reason for the call! What a bunch of useless *********** peoe, oh and to still tell me that i am not his boss so i cant demand to know where they got MY number from! The nerve! He wants to sell his **** but isnt even curteous to the person he wants to sell it to! How the hell do you explain that!!! Do NOT EVER PHONE ME OR MY HUSBAND AGAIN, we do not want your phones from your rude useless call centre agents
