Expensive services,bad customer service

Ive sent emails to standard bank regarding few concerns but they never responded to my mail.Even phoned them couple of times but i had trouble speaking to the agents or they just transfer me to the wrong agent who cant assist me or just say for a ********** transaction they can only come back to me in few days but never did,after contacting them numerous times.Their bank cost is extremely high and their investment plans is ridiculous. They dont even show on the draft of the different types of investment plans the percentage of interest tht will be paid out in a month only annually I think thats how they get people to invest with them.You dont even get 1% of an investment of 2000 but it shows save 2000 and get an interest of 7-8.Im unemployed but i still pay a service fee monthly also.
