Metcredit review: Harassment through phone calls and text messages

My friend Douglas Middleton passed away 2 years ago. Since his death I’ve been receiving phone calls from Metcredit for 2 years regarding his debt. I surmise he gave them my number to avoid the repeated phone calls. At first the phone Calls from Metcredit were periodic, and I informed them that he is deceased, I have no financial ties to his estate, and to please remove my phone number and kindly stop calling. It’s a different caller EVERYTIME and I keep giving the same information to them and to please stop calling me. The past couple months it’s phone calls from Metcredit EVERYDAY week day disturbing me at my workplace and causing me more stress more so now. Since they keep calling me with a another number everyday they keep disturbing me. I am now considering legal action since they have been harassing me for 2 years and won’t stop!
