Client claims that he gets 0 calls while Ads report shows otherwise

I have this client in Minnesota that runs a window tinting business. We run google Ads to his business profile. Recently he is claiming that he gets 0 calls to his business, although the ads are active and he gets charged everyday, and the campaign report shows that he gets about 30 calls per week.
What could be the issue here? He keeps saying that a competitor is hacking him but I don't believe that story.

Show him proof that you have sent calls to his busness. If you are using a 3rd party forwarding number then show him proof from there as well.
30 calls sent per week and he claims ZERO calls received ? If you have sent calls and provided proof to him and he still stands to his point, then stop sending calls, do not do business with him. He may perhaps be a dick who is unable to covert any calls into business, not even 1 out of 30 calls a week !!!
For pay per call type of leads you will for sure have more than enough customers.

yes I did that, I even read out for him some of the numbers that called (Google Ads keeps a call log for some numbers and displays others as "unknown")
I am not sure if he is lying or he just does not pick up the phone, but I worked for him for 7 months now idk why he would start lying after all this time? I am guessing maybe there is a problem in the Ads manager itself? or is it just impossible?

@mrwnmero Are you using a Google provided forwarding number in the Google Ads campaign or a 3rd party number ? Various things in Google Ads are bugged since the last few weeks. Hence their call reporting (if using Google forwarding numbers) may be bugged as well ? I am not sure, but could be possible.
What you could do if you are you using a Google provided forwarding number, is change that or create a new campaign with a 3rd party forwarding number. But, if you are using a fairly new Google Ads account in that case be very very very careful, as nowadays fairly new Google Ads account often get suspended even if some small minor changes are done.
With using a 3rd party forwarding number, you can be certain with their (3rd party forwarding number's) call reports and even after that if your client claims no calls, inspite of you sending calls, then the client is a dick. Sometimes clients with whom one has done business with for a considerably long time also become suddenly become "dick" in nature. Hope that does not turn out to be the case, though.
EDIT : What @tipsavvy has mentioned below is also very helpful. Many 3rd party call forwarding services have call recording feature. If you do this, do not inform your client about your side of the ad campaign that you are changing the call forwarding number & anyways you need not inform him : just do it, record any and every call and if even after that he says no calls, then reveal call recordings to him and the rest is upto you, as to what you decide to do about it.
But, if I am in your place, after the above scenario (if it is so), I would hold him by the balls and make him pay for ALL the calls that were forwarded to him as leads.

If you're selling leads then you should be using a call forwarding number where you can record the conversations.

change tracking call... to 60 seconds..
