This is UNICEF call and harasses me daily. The calls are to a UK mobile but since I live in France each call costs both me and UNICEF money - far in excess of my original text donation. This is infuriating and immoral.. It should be stopped meanwhile I will NEVER respond to a text appeal again.dobog.

I am being bombarded with insurance claims calls at the moment to my mobile phone that I use for business calls. This number has rung me twice, 1 week apart and nobody has been on the end of the line. TPS have registered my number so I should not be getting silent calls

I try to keep my mobile number private. It was until I donated to Unicef. Now they keep spamming me for more. I await calls from other organisations because Unicef will most likely sell the number on

When they call then cut off even when you answer. United.
