-what date you signed contract with o2?

-what date you have send cancellation letter 1, 2 and 3?

-how did you send letters? normal letters? or einschreiben/rückschein?

you only may cancel contract within 14 days after signage! and in own interest you should do this  with einschreiben/rückschein which you get at the post office. so you can prove you did cancel.

sorry, man, its no problem to contact o2 support by phone. why didnt you succeed?

in 4 to 5 months yo must have received many invoices and reminders. why did you not react early when there still was time?

now o2 has given case to debt collector. invoice will now explode...

looks like you are now on o2 mercy.

Hi @Susheel,

thanks for your message concerning the cancellation of your o2 my Data Spot-tariff.

Did you receive a confirmation of your cancellation?

In order to check that, I have just sent a private message via @o2_Support to you.

Please reply there to my request.

Afterwards, we will come back here to this public message.

Loving greetings,

Tobias
