Did Rav Mordechai Sharabi ZT"L Distribute Amulets?

There seems to be an argument between Rav Benayahu Shmueli and others on whether Rav Mordechai Sharabi distributed amulets or not.  There is apparently a famous amulet that is attributed to Rav Mordechai Sharabi.  Rav Shmueli, who took over the Nehar Shalom Yeshiva from Rav Sharabi, claims that it is a forgery. 

A family who asked Rav Shmueli for a blessing for their ill son also asked for the amulet.  He responded that there was never such an amulet and whoever claims that Rav Sharabi made such an amulet is frauding the public and using Rav Sharabi's holy name falsely.  All his life, Rav Sharabi opposed amulets, Rav Shmueli claims.  He further stated that whoever claims to have such an amulet is not telling the truth and is preying on innocent victims in their time of need.

The Refaeli family, who are in charge of the amulet, told Kikar Hashabat that they don't want to cause Mahloket, but they assert that they are holding onto the amulet that they received directly from Rav Sharabi, who told them to help people with it.  And it has helped people with health, fertility, and Shidduch issues, they say.   It also has support from Rav Ovadia Yosef Shlit"a,  Rav Kaduri ZT"L and Rav Mordechai Eliyahu ZT"L.

So in this Mahloket in Metzi'ut, who's right?
