MBD Harassment Company

I receive a phone call on a daily basis (Last digits change every time, but the 041 260 always the same) but when I answer there is no one on the other side. After numerous efforts from my side to call back I got through to a call centre lady who could not give me the reason for the daily calls because "MY NUMBER IS NOT ON THERE SYSTEM". I requested politely to remove me from their system, this was more or less 3 weeks ago, still get my call every singe day and when I do answer still no one on the other side. This is now becoming pure harassment. But if I google MBD, it is clear that this is their modus operandi and they clearly get away with their harassment tactics
