Overcharge by NS on Subscription dal Vrije
on the 30th July I bought the Dal vrije for 49 euros. On the 3rd August they cancelled my subscription saying I had an outstanding invoice form June. But there was no sign of outstanding invoice in my portal nor any previous emails of direct debit failure or payment reminder.
I paid them with the link they sent together with my subscription cancellation email. However the refused to restore my subscription cause the promotion ended.
Then I recieved an invoice of 33 euros for the 3 days of subscription that was active. I still dont understand how come they are charging me 33 euros for 3 days for a subscription which was 49 euros for a month.
Their chat doesn't work. I keep calling them every day. they take 2 hours in total and try to confuse me and then says sorry call back tomorrow.
What can I do?
