NO CLIENT'S SERVICE AFTER SALE WAS MADE

When I opened a tax free investment account the sales agent was very active and pretending like i would be receiving the best service from sanlam.

Well until i switched bank account to Nedbank, first it was almost IMPOSSIBLE to change my banking details with them and now no one even bothers to follow up with me and find out how they can assist me as my debit hasnt gone off for 2 months now.

At this point client's service is non existent,i dont even know who to contact to assist me sort this out.

What happens to my account? Can i get what ive already invested then and try old mutual or???!!
