I feel your frustrations...I'm a victim too... I also subscribed to the FB38 recently in May.
I realized that I got the stupid SMS Content Services after I found it weird that my bill becomes more expensive after each month!!!

At first it was only RM1. So, I didn't care. Then the next month June was RM4. I thought maybe Celcom charges for checking my data status - sending Bal Status to 28882. I still didn't bother to call Celcom. Then July statement shows RM6!!!
Can't be so expensive just to check balance status, right??? So, I called Celcom to enquire and they told me it's the stupid SMS ads!!! They gave me a lame excuse that I could have "accidentally" replied to the SMS and have subscribed to these advertisements!!!! Total BSl!!! There's no way that I would have subscribed to these ads.. why would I do it when I hate these ads??!!! I always delete them straightaway and don't even bother to read them when I received them.
So, how can it be my fault?? When I signed up for the new FB38 package I didn't sent any SMS to 25533 or 25544 before. So, why and how did these 2 numbers sent ads to me??? It should be Celcom who sent them to me!!
So that means
Celcom cheated and robbed me for I had to pay for stupid useless ads..and they won't refund me!
CHEAT! CHEAT! CHEAT![COLOR=red]
Anyway, even replying STOP ALL also get you charged! Total BS!!! When I checked this month's bill (Aug) I was shocked that I'm still charged with RM10! Why?? Because they say that my STOP ALL sms was sent on 23/08 and my billing date is on starts from 14/08. So, I probably still receive the sms during that 10 days.. I can't imagine if I didn't sent the STOP ALL sms...what would be the charges??
I called to complain again and the lady told me that she'll help me to stop all 5 digit numbers. Let's hope it works this time...
Actually I think if you fight for the amounts, they would have to refund you. I will let you know if I have successfully get back the amounts.
