I've had 3 calls in the last 2 days. When I answer, there is silence for 2 seconds then it hangs up. Even if I say hello, it hangs up. I've used the block function on my phone now to stop the calls coming through.

I called back number (07) 3613 6288 reached voice mail for a charity company but did not say the name.

Unfortunately, the good charities to which we all donate, on-sell our phone numbers to call centres for other charities.
I get calls from '07' numbers every so often, each time they change slightly (last digits etc). I find it highly annoying that my generosity towards a charity, gets rewarded by them, by giving my number to others so they too can harass me for money. Blocking , or not answering is the best solution.

This now the 3rd number (being a 'charity') that has called me in less than 24 hours. My name and number has clearly been passed on by some unscrupulous company .

Calls on the home phone and no message left, then the mobile rings and then they hang up when I don't answer. called the number and no one answers. At least twice per day and at dinner time

wanted money

Called by this random number at dinner time. Just another for the block list
