MTN robbing clients coz no1 is speaking up...

MTN use 2 be da best network but recently I don't know what 2 say...1stly data is a big thing these days but they decided 2 bring da what's app bundle 2 clients at R10 for a whole month...After 2/3mths da price changed 2 R30 but guess what now it's 20 days...How is that possible that da price gets higher and days get shorter...Then wud da normal data we pay as u go clients pay R160 for 1gb and wudout that ur what's app only works when u on da app so u still need normal data...So if u got data left over u cud buy da cheapest bundle like for R10 and ur data will carry over but now app data bundle is R150 for 1gb but can't be carried over any more. ..I don't think this is fair at all coz we are paying 4 it and we shud have da ryt 2 a non expiry date coz it's our money and we need 2 use it how we see fit...Imagine having sooo much data and waking up on a morn and it's gone...Is this customer service???Trust them 2 send a message or try 2 post a reason but they shud actually find a solution and give us our data wudout an expiry date and make da what's app bundle cheaper if it's got 20 days now coz R10 was 30 days but R30 is 20 days...What a joke
