[members-discuss] We bought a /22 and +400 IPs are listed in SORBS

Hello, the last month, we have bought the prefixes: 188.213.4.0/24 188.213.5.0/24 188.213.6.0/24 188.213.7.0/24 This IP blocks seems have been used in the past 2013-2015 to do SPAM activities by the previous owner of the IPs, and +400 IPs are listed in SORBS database. Their website is going really slow, and we taken +5 minutes to open a case for just 1 IP, some hours later we got a confirmation that the IP has been delisted, but doing this, we will need +30 hours opening cases... We have contacted SORBS, opening a ticket, asking for a full delits, but we have not get it any response by them. Now we have tried sending a fax... Anybody know how to contact them to get delisted?
