Fnb disappointed loyal customer

Today I checked my banking App and saw that's there was an EDO collection attempt shown on my App. I called through to FNB customer care who kept transferring me from pillar to post. No one in each department could help me or tell me what it's about and told me they can't stop it. I can't understand this really! I'm frustrated that the bank iv trusted in for more than 20 years can't help me with this query. This is not on my debit list and I can't understand this and I'm very disappointed in FNB!
