I summarize my grotesque situation: asked for line move, after 4 months of reminders and missing line I communicate the withdrawal. After 60 days (calmly!) From the withdrawal, they issue closing documents and their refund payable after a further 120 days. Upon expiry (and payment) they realize they have made a mistake and reissue new credit note payable after a further 120 days. So: service stopped at the end of January 2019, left without a line for 120 days, refund paid (perhaps, as long as they don't realize they made another mistake) in April 2020 (420 days ...). I would like to point out that all the fees have always been paid regularly. The serious thing is that, despite having admitted their mistake, they do not care in the least to follow up on their commitments. I believe and hope that the future for Fastweb is rather black if this is their way of following customers. Small and medium-sized companies cannot certainly operate in the same way, but must respect their commitments and pay attention to the customer; why can Fastweb unilaterally make good and bad weather with money that is not his?
