Bad customer service

Good morning. I app**** for a Woolworths credit card which was provisionally approved. I called your customer service and spoke to two unfriendly consultants. One I think her name is Ziyanda the call cut while speaking and no one returned my call and I called again however couldn't finish the application with the 2nd consultant due to time, she then advised she will have someone call me at 12.30pm or I can go to any Woolworths store to complete the application. After work i went to the Woolworths in Canal walk and i was told i was suppose to bring my payslip and proof of address which i left at work as I was never told by the two consultants. I'm really dissapointed at your service. I want to cancel my application, please inform of the process.
