bundle no longer available with no prior warning

I have bought R1800 telkom airtime with the sole reason to convert it to data for the 60g+60g data bundle (as I have been doing for the last 2 years x 2). This morning I have found that it is no longer available with no prior notice that it wont be available. I now have R1800 airtime that is totally useless to me. The products that its been replaced with is totally nonsense. Its a *******. I thought you are supposed to be the cheapest but now you are just like the other networks just upping your prices and *********** the consumers
