Telkom Mobile Invoice ***

Every month i receive an email stating that i must open the attacchment which does not appear on the email. I have in the past reported this to social media with the hopes that this will be resolved but still i receive the same thing every month. They give me the telkom mobile invoice (Telkom Mobile Invoice ***) but no attachment to open. When will Telkom get this right for me to see my itimzed billing which i get charged for every month, or are they doing this deliberately or *****ing from me!!!!!!?
