@AbdulRahman Bahaa You also may be able to use openssl to generate a PFX using the files provided by GoDaddy. Check out this stackoverflow answer. Also have a look at https://azure.microsoft.com/en-us/blog/obtaining-a-certificate-for-use-with-windows-azure-web-sites-waws/ on how to use digicert in addition to IIS to create your PFX.
Hope this helps.
