Hi im a celcom prepaid user ( cant afford using postpaid, and my plan is the one that has no expiry date until 2021)
Since im not a heavy user and I always wondered why my prepaid balance always get to 0 quickly eventhough I dont really use it . Turns out that ive been charged for service charge and I didnt even subscribe to any of the (funky) messages. These are the messages from 22990, 39919 the one that has mms sent to me. Do you guys have any idea on how to stop it? or should I just get a new number.

here is the history

Thank you for the solution. Its supposed to save me money by using prepaid but end up the other way around.

I tried doing that, but sadly my credit was insufficient.

TS here, asked the customer service and their reply was to send STOP MMS to all the five digit numbers. Then, I asked them what measures can I take so that this thing will not happen in the future they said they cant really do anything since its comes from 3rd parties. So sayang want to change telco tho cause I want to find plan that has no expiry date or very long expiry date.

Write to where? Sorry, Im so noob.
