Solution provided by Web Chat person but disconnected before I could say ys
I chatted on the web chat and explained my problem (long time UPC customer with full tv, landline and internet just moved over my mobile abo with European data pack which I had to wait to months for and now can't actually use).
The lady Sarah offered me 30 francs credit as an exception, since I was stuck with my abo rate. She asked me to confirm this was ok, and then the chat stopped working. I never got to say this way fine... How do I know now if I get this credit?
I have tried to reconnect to the web chat but did not manage, it said it was full.
I have the copy of the transcript via email from web chat.
