Shell Voice

We have been dealing with Shell Voice for around 7 months and things were more or less fine. They paid late but, this isnt something we havent had with other customers as well.
Since October 2018, we are no more able to connect to anyone there. The people do not take the phone, Skype is off and emails are not being answered.
Further to that, we received info that another customer of ours had the same issues with them.
They owe CloudNow GmbH the amount of 1.926,32 USD.
Unpaid since October 2018.
