Mbd - worst service ever

I would have given a -* if Hellopeter would have allowed it.... So irritated! My mother passed away on the 20th of February & we have send ALL the relevant documents on the 9th of March 2019 to all the parties involved to have her GAME account closed. Me & my brother are getting non-stop calls from MBD's consultants looking for my mother to pay her account. WHAT THE HELL?! We have send numerous emails, had countless harassing phone calls and sms's from DIFFERENT consultants on a daily basis, and still they claim they have not received our paperwork. Do the MBD consultants actually work in the same building? Do they not communicate with each other? Do they not update their systems?! I will send out emails and harass them until I get a response and have this matter solved and CLOSED. This is ridiculous!!! WORST SERVICE EVER!!!
