I was just wondering how long spark will keep my call history for if I request it through the call investigation centre? 

Presumably they will email my call and text history to me so I am wondering if they will have a record of that history in their email for a long time? 

I am not sure how comfortable I am with having my call history always accessible if they keep it for a long time once I request it as I kind of like that they only keep records for a certain amount of years. 

Does anyone know how long it will be kept for? 

If they no longer have it after a very long time, say 25 years, even this would be good to know as it would be good to know it is no longer accessible after a certain time frame even when you've requested and received it over email. 

Does anyone know if you can request for your provider to delete your call and text history, even including the call history you request and receive via email?

Thanks.
