it is for the second time that i sent an email to standard for service. in the emails i sent, i never received any response it does not matter how urgent my requests are but standard bank just ignore those emails. i sent email today asking about my cheque that needs to be cleared and the cheque was deposited in my account last week thursday and i sent an email asking them about the short way that they can help me to clear the cheque because it has been deposited into my cheque account. till now there is no response. i do not know what to do for this people to understand my frustrations. i have been with standard bank for 15 years. i need that money i want them to help me with a way to access my money because the money is there but they have to wait for 10 days to clear the cheque, so i am now on 4th working day for the cheque to be cleared, i assume there is another way they can do to clear the money. i am frustrated with these people.
