Accounts - NOT downloadable via mms

Every month I receive this MMS message from Edgars with a Statement I need to download... I wish it was down loadable! I have a Samsung S5 Mini so it's not that my phone is unable to do the job. So... I've just been putting money into my account... I am sure its covering the monthly instalment as I don't get any threatening calls. I also don't remember ever enabling this form of communication - I'd rather receive my statements via email if you no longer want to post them. I've also had to block calls from a call centre phoning on behalf of Edgars wanting to sell me some form of funeral cover - thanks to automated calls, majority of the time I get an engaged tone when I answer it - VERY annoying.
