Whatsapp data bundle last anymore

I am really disappointed in the way your whatsapp data bundle doesn't last anymore, @ 1st I thought I ws imagining things but for the bundle to literally last 4 days, that's just a *******, you keep changing the amount of data being off, next thing it's gona end up lasting 2 days..... Well I feel that I will be moving to the best data network which is Telkom mobile because you guys are playing with us......
