mtn false advertising data sales

bought a "remake 2020" data special on 30 days it sais 300mb data "+" 300mb data for R10 on your mtn app. i received a sms that ive purchased 500 mb night data + 50sms.which is totally wrong .then when i go on my mtn app it sais i have 300mb night data.where is my 300mb normal 30 day data ?. i called customer care at 20.43, spoke to disemelo moquen who informed me that its 300mb day bundle which will expire at midnight tonight and 300 mb night data.i have wi fi at home that's why i bought this package for the 300 mb to use as data if i might need.but he was arrogant and could not understand and after a long unhelpful frustrating conversation he sais i must call customer care for this issue but he is a customer care operative.your advert clearly states "30 day 300 mb data + 300 night data!!!.".i asked for it to be reversed and he rep**** he cannot.your mtn app is clearly misleading.ive done screen shots of the app as well as the sms and the data given.false advertising if your app sais its 30 days then its 30 days not in 5 hours your data expires.come on how many people have been misled by this !!!?.This is not on !.
