The last week or two has seen a big increase in scams by means of phone calls either to landlines or mobile,not only myself but users on several local forums such as boards.ie have been posting about the same. Perhaps its just a phase but these tend to come and go and for weeks on end you hear nothing but now its an issue.
The first number is based in Nigeria second from Somalia and finally the last one is India… As per usual do not answer if you see these numbers and most importantly do not call them back. Block them from you device if it allows it.
