Sanlam Managers' attitude

I took out a R.A. with Sanlam last year. Later I changed my banking details, which was never updated by them. They called me I had to deposit the missed premiums to keep the R.A. they confirmed they will debit the following month on my new baking details I had given them. They never did. Now my financial advisor, informed my R.A. had lapsed and that we had to take out a new one. Their manager Bandile Msengana refuses to issue the R.A. it was never my fault that they never changed my baking details. This man Bandile Msengana has diminished my belief in Sanlam as well respected financial institution. I will take out an R.A. elsewhere. The attitude he gave me from word go, for a person to call himself a manager, yet he treats clients like that?? Thanks but no thank u Sanlam for a pathetic service, infect it's not the advisor l, but it's the manager Bandile that makes me think twice about this organization.
