SALES CALLS MUST STOP

I have never had an issue with FNB's service, but their sales calls have made me so angry. EVERY. SINGLE. DAY. They do not let up. I answered once just in case it might be important and someone kept me on the phone for a long time reading out legal documentation. I refused to consent to anything over the phone and they just kept going. Eventually I just said, "I do not consent to anything and I have to go", which is very unlike me to be rude. Then they actually phoned straight back! I ignored the call. I honestly don't think sales calls should even be legal. I use my phone for work and I cannot afford to listen to someone, trying to be polite, while I'm at the office.
