I was tricked into purchasing Elisa's subscription by Elisa's seller in Myyrmäki shopping mall. He convinced me that the subscription will start from the date I ordered (1.05.2021). But it started at that day. I've never put Elisa's sim card into my smartphone. And now, I have to pay for nothing. I will never use Elisa's service and recommend it to anyone.
I'll be happy to know where else I could write a complain for such terrible service.
