confused

being called by an fnb representative giving me the option of upgrading my account from cheque to premier, was dumb.if i say so myself. the polite young lady told me about the benefits.then i asked how much will the subs be monthly she sed 180. was told i will only be charged in September. the very next day 5th august there was an amount of 275 debited from fnb reason beyond any ones understanding. when i called fnb enquiries they had no idea.a query was logged, the consultant didnt even know that premier banking clients can call 24/7 she says i must call back. gosh i am really dissapointed.banking with fnb for so many years and i have this silly encounter. its been 5 days i have not recieved any calls feedback nothing. i calledfnb myself was told i will get a call back.. annoyed.still waiting.
