Stop f*cking Calling My Mum

Thanks! I have got repeated "Missed Calls" from this number but when I try to ring it back it says that the number is "disconnected". Very annoying because I have been trying to track something that I have bought and paid for on-line and thought that it may have been the seller trying to contact me.

Seniors Plus. First they phone to see if you have anyone elderly living in your home, then if you do, they ask if they can speak to them as they are conducting a survey and want to ask a couple of questions. A week later they will start hounding you to buy their (probably overpriced and unnecessary) products, saying that they will have someone in your area in a couple of days time. Told them a couple of times my mother is not interested. Last time they phoned they wanted to speak to Mum AND Dad which was upsetting because my father has been dead for 30 years.
