Problems in my iPhone 5

Hey y’all. So basically I’ve had this exact problem for 2-3 years, in regards to my iPhone 5. I took it to a phone repair shop to fix it, and they partially did, until the ‘Activation Lock’ kicked in.

I entered my correct email and correct password but

So I went onto my laptop

I can’t remember ever putting that email and I don’t know my ‘d.o.b’ tied to that account.

Thanks in advance for potentially solving this for me.
