absa dont want to stop phone me with sales ***

Absa does not want to stop phoning me to sell me insurance that i don't want and don't need . i have emailed them. phoned their help desk and did multiple calls. Nothing helped, canceling all business with them. Don't ever give them your personal information. They have no values, the simply give it out to anybosy that is willing to sell their products on their behalves. Don't do business with this company. Avoid at all cost. It is costing me a lot of money in phone calls to get them to remove my personal cell number from their systems. And they dont care about their customers
