MTN prepaid data price issues

Hello MTN, I have a bit of a problem on your prepaid network. Your data offers in particular keep on being updated regularly inflicting users with untimely and questionable data price increases without warning. This also being bought through your USSD codes that are confusing and deceptive, because there are a myriad of options for data, yet most of these options have the same data bundles for different prices. The one I'm referring to in this post is the most disturbing of all. All of a sudden you no longer offer 5 gigs of weekly data at R49 but rather R100. How does this make any financial sense to mark up a product over 100% overnight. Last week I paid R49 for the same bundle, this week I'm out of pocket with my work and overspent on airtime for the month already. I'm really disappointed in the fact given the sheer magnitude of the shifts in your prices. Could you please look into it and try to accommodate users through an easier options setup to get the best deals and reliable data pricing we can bank on. Thank you
