Thuis Company needs to SHAPE UP!!!

Thuis Company needs to SHAPE UP!!!
My son is a member of the National Geographic Magazine for at least 10 YEARS.
For some reason last year everything was moved from Belgium to the Netherlands and he received a new members number.
Now we are struggling to get everything right again! They pretend that we did not pay. which is not the case!
We called them already 2 times by phone BUT STILL nothing is in order.
IF they cannot shape up then we will give up the magazine!
Meanwhile I would suggest to EVERYBODY NOT TO TAKE ANY SUBSCRIPTIONS FROM THIS COMPANY! They do NOT deserve it!!
