Misleading quotes from on their website

A week and a half ago, i did a quote through Nedbank's bolt system for a funeral cover. I was happy with a quote and i requested that i get contacted back in order to arrange cover for my mom. Few days went by that i ended up calling them and after holding on the line for about 11 minutes, someone picked up and they said they are going to transfer me to the relevant department and i waited until the call returned to the same person only to be told that i will be contacted tomorrow a be transferred to the relevant department. till today am waiting. After 2 to 3 days i received a call from their call centre and they asked for my mom's date of birth only to be given a different quote and i told the agent that i want what has been indicated on the quote that i have been given. They agent couldn't assist. I then sent an email to the email addresses that have forwarded me the quote but till today no one is responding to me. Why would you mislead me into believing that i can get a funeral cover at an affordable quote if you will change the quote when one get interested. I demand to be contacted back and be offered the same quote as the one given to me. All people that were on the email, didn't respond to my email either. This is one of the reason why i cancelled a business account with you and most probable if you fail me here you might not even get any business from me.
