Absa has no client services and does not listen to the client

After receiving a written guaranty from absa management that I would receive no more advertising and harrassment from them, and after absa offerd me a amount of money to make amends for the harrassment by absa , again I get mails from absa to sell products. Absa just doesn't listen to its clients and the clients requests. I have been a client of absa for 35years and absa has fallen in client delivery standards to a very low.
