I have a client that I was running for him a search ad, to make customers call his phone number, in my Adwords dashboard the phone number was clicked 176 times during the last month (1-31 December), the problem is the client said that it is ONLY (7 people) call him during this period!!!
I just wonder is that may occur or what? I don't understand why he is said that, so if anyone has such this situation tell me what to do?
you could see the screenshots from my Adwords below
