Bad Service regarding a Will

I'm really disappointed about the bad service, my dad passed away on the 1st of January 2015 and I took my mom to the branch Nico the Branch Manager assist us regarding my mom's new Will. My mom is blind for the last 2 years and in a wheel chair and stay in Hendrina Old Age Home. Shaune phoned me to collect the Will , I went all the way from Witbank to Hendrina and took my mom to the Police Station for finger prints, Nico told me the Old Age Home must sign as Witness, the Suster Eurika told me that they have a new rule and are not allowed to sign, I phoned Shaune from the Police Station and asked her if the Police can sign as Witness and she said Yes that's no problem. I went to Shaune the same day and handed in my mom's new Will. I received a letter from Standard Bank \Legality Failed Will "because the Commissioner of Oath also acted as Witness on the Will which is not acceptable. I phoned Nico 2 weeks ago he said he will come back to me left a couple of messages with Shaune"
