Appauling delay and turn around time not met.

I have been struggling with Tyme bank. First, I visited two different kiosks, and you guessed it neither one could assist me in changing my number nor can I print a card. Then Eventually I logged a call with the customer service on the 6th of February. Where they advised that they have to down grade my account to change my cell phone number on their end. And as soon as I am able to access the account and update all relevant information, they will upgrade it again. There e-mail promised me resolution will be on 11 FEB where I phoned on 11th the agent told me that it would be resolved in 2 hours 45 minutes. Which it was not. I phoned again. And then got another mail just past 15:00 the afternoon advising it has been resolved. And guess what nooooo It was not. Needless to say I have phoned them on 6th February 4 calls one was 2 min and 23 seconds, 11 min and 29 seconds, min and 24 seconds, 8 min and seconds - 10th 5 min and 11 seconds, 11 Feb - 4 min and seconds, 8 min and 21 seconds, 13 min and 49 seconds, 6 min and 55 seconds, 16 min and 5 seconds - 13 February 7 min and 52 seconds - Then today 15 min and 29 seconds... Still nothing... PLS PLS PLS tell me how difficult this task seems to be. AS I believe a turnaround time from 6 to 11th which is 6 days is absolutely ridiculous to start off with. Then they don't even meet that target. Now 3 days further which has the turnaround time at 9 days still no resolve. IT really seems like a person should log onto the system in the back office. Change the number and save. Maybe a 5 min task at most. But 9 days... Come on people really . At the end of the line the customer suffers but seems that customer does not mean much to Tyme bank.
