Hello, thank you for contacting me and welcome to the community.
I would recommend you to call our technical support directly, you just have to write down the exact details with date and time when these interruptions took place. Then our technicians can make an analysis and if necessary a ticket to our 2nd level. The number is 0800 66 88 66.
Thanks for your understanding. Best greetings, Cem
