Activation Error and No Easy Phone Code

Hello,

I have received my card and card reader 10 days ago. I also received the e-mail and the link to activate my account. I didn't receive my easy phone code. When I try to activate my account I always receive the above error. I called Hello Team multiple times as I was not able to contact. 5 days ago I contacted using the French line and luckily the lady tried to help me, indicating that the technical team will get in touch with me. It has been days and I am still not contacted. I try to call again but English line is always busy. I wrote a complaint e-mail yesterday, still nothing. Last night I received an automated reminder to activate my account or my account will be cancelled. I tried to activate again but still the same error. Should I let it be cancelled and go for another bank?
