Rude Telesales Staff

Dear Standard Bank, When trying to sell life insurance to customers, please request that your telesales staff say "thank you" and "goodbye" before putting the phone down after I have politely declined the product they want to sell me. I find it very rude to be hung up on like this and its not the first time its happened either. I will not, on principle, take any products such as this one, through standard bank if i have to deal with such rude people.
