Hello ​@Bimal,

those are not so nice experiences indeed.

I have ended the video game conscription for your number immediately and asked for a refund for a payment already scheduled for it.

Could you already undertake steps regarding your contract?

Best Regards,

Gerrit

Oh my god , what a fraud company is o2 . 

on the date of 19 march 2026 , I received a call from o2 person who is providing me an additional o2 sim card free of cost . As per him , mu current bill will be reduced from 23 euros to 10 euros per month and o2 is giving me an additional o2 partner card free of cost in which i get unlimited calls data and sms . 
I confirmed many times that is it true that my current o2 sim card bill will be reduced to 10 euros per month from 23 euros . And he said yes many times . And surprise thing is that the call was recorded . 

After giving him consent to give me o2 partner card , I received an email in which i see one time activation charge of 40 euros and the bill for new partner card is 10 euros per month . 

Next day on 20 march 2026 , I call to o2 customer support immediately and tell them about everything . 
And now the o2 customer service person is telling me that sorry the information provided to you about partner sim card must be wrong . 

Then i immediately asked him to cancel the partner card and he did it immediately . 

Dear o2 authorities , please whenever someone ask that he does not speak german and only speak english , please do not make fool of him . 

I openly condemned the shameful and fraud acts of O2 . 

O2 is running only on the behalf of fraud that he do with the immigrants as we do not speak well german . 

In my life i never see this much cheap acts from any company to capture their customers . 

If o2 is reading this , the person who cal me for the partner card has asked me for the consent of call recording and i said him yes to record it . please check the call recording . 

Same this thing happened to me in the month of august 2025 and my bill has been increased to 23 euros per month from 20 euros per month . 

If you have any respect dear O2 representatives or O2 authorities or if you have any shame please resolve my both issues of monthly bill and punish the person who did fraud with me both of times . 

Please note my comment!

Oh dear, that is another bad experience with this unwanted contract, ​@Bimal.

I could check, it has been revoked already.

Best Regards,

Gerrit

Yes it has been revoked already because i did it by myself . 
But what o2 will gonna do for me . 

Will o2 reduce my monthly bill to 20

euros per month as before and make the contract valid untill april 2026 as it was before . 

As my contract has been extended on the basis of a lie and my monthly bill has been increased after saying me that my bill will remain the same .

If the contract is revoked, it will be reset to its original state.

The additional contract has been revoked, ​@Bimal, your original contract is unchanged.

Best Regards,

Gerrit
