terrible service!

Using my banking app, i purchased R50 airtime. I noticed it did not come through and reviewed it, only to see i had made a mistake with the last digit. I then purchased again and called them. Firstly, the number listed at the back of my card for customer service, when i got through they told me they only deal with credit cards, then i was transferred. The next dept then said they do not deal with airtime purchases and transferred me yet again. The next dept said they only deal with electricity and other purchases but not airtime. She asks me to hold, and the next thing i know i was transferred again! The next person put me on hold to speak to the department i was just with and comes back to tell me they cant do anything about it, and then my airtime i had just bought, R50 ran out! I am so frustrated and disappointed. They provide you with the facility to do a transaction, but when something goes wrong they dont want to help you. This is looking to be the straw that is going to make up my mind to close my account and move to another bank. Pathetic!
