Irritating calls from Clientele

Not once have I asked to be contacted by Clientele nor have I ever given permission for my information to be shared with Clientele, yet I am harrassed by calls from them. I have asked on record (as their calls are recorded) to not be contacted again and have even spoken to supervisors and managers to have the calls stopped. Yet I more than often have to listen to some robotic voice trying to sell me insurance of whichever type. I have insurance, should I die my wife will be able to pay for a lovely send-off and continue living rather comfortably afterwards. I DO NOT NEED NOR REQUIRE FURTHER INSURANCE. These calls only send my already rather temperamental blood pressure skyward. Dear Clientele, remove my name and number from any and all of your clearly ill-gotten lists, I am not in the least interested in acquiring any type of insurance from you. I have more than adequate funeral cover. I have more than adequate life cover. I already have a very accomplished lawyer so I do not need legal cover. My phone number is to be used ONLY by my architectural clients, my wife, really close friends and family. NOT by Clientele attempting to hawk policies. I assume and accept that you find this in order. Stop harrassing and just plain irritating me and wasting my time. Should you require further information you are welcome to comment here so that you can put a stop to your unwanted calls.
