WiFi Password

Hi All ,
We're the new owners of a place on Marina del Mar 1. Came out for a few days last week, but didnt have time to get our WiFi reconnected.
Back in UK for a few weeks , but can anyone put me in touch with someone from Res & Owners Assoc for MDM1 who we can get the WiFi password sorted from , which i gather costs Euro 35.
Previous owner didnt disconnect the WiFi , but , as I'd have done , didnt pass over the Password.
Any names , email addresses , hyperlinks would be great , Thx ,
Rob Hughes
