Cant access my funds - banker does not respond

I became the authorised signatory for a Trust account in 2016. This took approx 6 weeks to get hold of the banker and get all doc complete. The account has been dormant, however I now have to make some payments. 1. My internet transfer limit has been zeroed 2. Have tried online, through call centre and by visiting a branch to get access tio the funds. 3. Apparently the only person who can do this is through my "nominated Banker". 4. Have been trying since Wednesday last week. No response to emails, to emails sent by the branch or to calls.

Branch also told me the change of signatory does not appear to have been done despite all docs being submitted and me meeting with a banker at Fourways Crossing and providing all docs face to face.
