They are not suspecting your marriage. They said your watch is fraudulent... Buy a scratch card enter
@Mimikoms Go to your registry and do a marriage search in Canada, they will give you a note showing you have never been married before or if you were in a common law relationship explain in details how, why and time relationship ended with any supporting Document E.g child custody if any and your CRA taxes showing your marital status before your marriage and after.
For waec check the DOB and if your husband wrote his waec in the year 2000 it should have his passport photo on it, u can send the scratch card if possible write a letter explain why you are sending it to them and include the website on your letter. Also add new stuffs like screenshot whatsapp chat, SMS, call logs, western union, flight tickets etc but include them on your supporting document. Make a list of what you are sending to make work easy.
