They just want to sell you products

Coming here to complain, again, as a private client. I receive endless marketing calls from FNB trying to sell me all sorts of things - I don't want them! Stop calling me and trying to sell me a product i don't want! Why don't you take me off your marketing list! I have already complained about this in the past (***NF) and my ticket was just closed. I get +- 8 calls a day and when i answer the line just cuts. Please stop!
