Unprofessional sevice from Rcs

I have called RCS customer services to ask them to close my RCS card, I was holding on the line for over 30 minutes and the call gets disconnected, I call again and the samething thing happens, this is very unprofessional,as this is not the first that this has happend. I simply don't have hours to hold on the line and than get disconnected, I have had enough as their service is pathetic, I want to close my account immediately, I have an nwj rcs card, which I was **** to when I opened this account nwj advised me that its 6 months interest free, which is lie and no monthly fees when your account is paid off. I didn't now that they have to lie to get customers to open rcs account
