Unwanted Mobile Insurance Activation Telefonica

Hello ​@hassansyed .
welcome to our o2 Community 😀
Unfortunately, I do not have access to your data as you are registered here with an interested party login. 
You must have received an e-mail about the conclusion of the cell phone insurance. 
You could have canceled the cell phone insurance within 14 days. 
Kind regards, 
Solveig 

I didn’t receive any email or any login details because they didn’t ask for my email when I purchased (27th December) the phone at the store, they only asked for my phone number and address and of course bank details. I also didn’t receive any phone call for this. My phone number is XXXXX, and the last four digits of the IMEI of the phone are 3984. Also, initially, when O2 sent a confirmation document where the reference number XXXXXX was written, in that document, they also didn’t mention any premium insurance, so how come they signed up for insurance I didn’t ask for. Furthermore, the insurance number for Telefonica is XXXXXX I also emailed hv@telefonicainsurance.de

but have got no response from them.

Please help me out as I never received any info from O2 and I didn’t accept any insurance
