BAD BAD BAD

Since I upgraded my Contract in 2021 I got a certain amount of data. Now this month my data is totally different. Why can you have the same data for almost 2 years and now... If I call the call centre they are rude and they try to tell me this is how my contract was from the beginning. I have all the sms messages to show the data and the minutes. Just stop lying, MTN is becoming the worst service provider.
