Changes are not always for the better :-(

I have used an 8*ta ****le for the past three and a half years. ***. Every second month I would purchase my voice data 3Gigs for use of two months. In order to use it on my desktop computer, I would convert it to computer data and have 3Gigs for R159.00 for two months to access my email every alternative day and some internet googling type work. Two months ago, they put up the price Name: <br> Number: TelkomSA<br> Content: <br> <br> \Your account was successfully loaded with 3GB Add-on Data that will expire at the end of the next calendar month.<br> Time: 16/08/2015 20:10:15"for R199.\""<br> <br> I have accesed my email about three times since and the latest message reads<br> <br> \""Number: ***<br> Content: <br> You have 100 MB left of your Once-off All Networks Data. Dial *188# or login into [URL Removed] to get balance information.<br> Time: 24/08/2015 11:19:43\""<br> <br> I called the call centre to be told that they have changed their memorandum of understanding with MTN(?) and use \""roaming\"" rates"
