Disrespectful TFG telemarketing calls

Tfg foschini pty ltd group calls me everyday with thier offers and subscriptions to my tfg account, No issues with that. My issues is with the telemarketing group who can't seem to understand the concept of declining an offer. Everytime i decline an offer i try to be as respectful as can be without being harsh to take into consideration these are peoples jobs to cold call customers amd offer subscriptions and add ons. My problem is that they cannot accept a denied offer. My latest call was from an agent by Chantal or candice who refuse to accept the fact that i declined my offer and as i was explaining as to why im declining. She said and i quote "thank you so much for your time" and hung the call. We are working class people and take the time to answer the calls and respectfully deny it so we don't get disrespected on the call. Utterly disgusted in that call. This infact will play a role in me considering to close my sportscene and American swiss account. I hate to be treated like this. Utter disrespect. Answer me this. Is this how you guys treat your loyal customers TFG?
