Unable to open file, told to get data/airtime

I wrote an email to Edgars Customer Service to ask for a plain text statement as I cannot open the mms attachment they sent me - the file cannot be opened. I got a very condesending reply : '... note that in order to view the MMS statement you will be required to have data or airtime... Zotha Ndlovu' Big difference in not being able to open a file and insufficient airtime/data etc. seeing that I could send them an email...

This is the second instance of bad service in less than 2 months. I didn't get any statement (and no, I did not erase it by accident) for a previous purchase in March. When I got an sms on the 8th of May regarding payment, I could not access any balance info online as there was another message blocking my account statement - 'You have to pay a bit before you can buy more...' I was not trying to buy - I was trying to determine what I had to pay. When I called the service centre, I was told an amount more than the actual balance, even after asking if this was the exact amount. This is now a credit in my account, but who's drawing the interest?

I know it remains my responsibility to make sure my accounts are paid up, but if you get charged late payment charges after not receiving a statement, getting overcharged when paying or getting unreadable statements, you can only start to wonder.
