can not log in

Hi, I have bought Avira Antivirus Pro yearly subscription for 1 device. For activation I need to log in to my account. When I input the correct email and password, then I should input a verification code which has been send to my cellphone but I do not receive it. The tel. number is valid, as I used it before for logging in. Then I created new user account, inputed some of my passwords one by one (others are still in the old account, which I can not log in), then bought new subscription for 1 device for new user account, but the licence has been sent again to the old account.
I understand, that I have paied not a big ammount, as the special offer was with big discount, BUT still I have paid twice and can not use it.
Please solve the problem with the verification code, which I need for licence activation or advice how to withdraw from 2 contracts
Thank you Lazaryan
