I am a tourist and I have been scammed by my accountant in Morroco...my only proof left are the massages which we exchange,are WhatsApp massages considering an evidence?

My accountant asked me 12000 euros to open a company, during the whole process he played a lot with me giving me false information, one day I fed up with him so I changed accountant when I was about to transfer my company, my new accountant, said my company is based on some false information, basically the place he rents for the company is not legit since the real owner is not mentioned in the contract and it has been a scam, I asked my old accountant to fix it to prevent more problem, he said you have proof that I opened your company but you don't have proof that I made you sign that paper ( since his autograph is not on the paper)...my only evidence is him massaging me and asking to meet me the same they I signed the contract and a text that he said ( as we spoke before I will look for the location)...are my WhatsApp massages enough to show his guilt? Thanks for your support and help
