Agent dropping a call on me

<p>It doesn't matter wherethere I'm being unrealistic or not .... you have no right to drop a call on me ... I called and waited 20min on the line with my airtime ... this is rude and poor customer service and disrespectful ... I'm a customer that is unhappy ... make me understand your business rules so I know next time and if you can't explain to me or listen to me .. transfer me to someone you will . I am so disappointed at this bank. How rude can you be to drop a call on a customer ???? And dont your dare say i dropped... my airtime doesn't run out... and I have full network coverage ... </p>
