Mail "Your benefits expire", but I didn't change anything. Can I get help in English?

Hi all, 

It’s my first time here, so I’d like to say sorry in advance if some mistakes.

I have an internet subscription from KPN, since 2019. 

About of 2 months ago, my husband got a mobile subscription, also from KPN, so combiing with our current internet plan (extra discount, etc..). It’s 10GB, unlimited calling and texting. 21euro. 1 year.

Today I got an email with the following:

Beste mevrouw Altuntas,
Unfortunately, your benefits will expire. Below you can read why the benefit expires and what this means for you.

Cancellation, termination or relocation
You have canceled, canceled or moved 1 of your KPN products. As a result, you no longer combine KPN Mobile and Home at your address. You will therefore no longer receive any benefits.

I checked my profile, application MijnKPN, and everything still looks fine. The invoices are ok.

The home internet subscription it’s also ok..

I tried to call to KPN but unfortunatelly my Dutch doesn’t help myself.

Can please someone give me some hint or idea what should I do? Or what is this mail about?

Is there maybe a way that I can have support in English?

Thanks in advance for any reply.
