Appalling attitude and service

I went to Old Mutual Randburg,I wanted to cancel my investment account due to un satisfactory delays and not delivering their promise in the time that consultant says. Zimkita is the lady that was dealing with my application on the 11 March 2016 . she promised that my application and everything will be sort in 5 working days. Today I followed up asking what's happening with my application. She didn't send anything to Head office nor followed up with me as a client. When I called she was very rude and arrogant. I called 10am,she told me she cant assist me as she is busy with clients, I felt that I'm not important to the entity. She only got back to me at 12pm.i asked for her to send me an email of what transpired on the day so can send an email to the lady at head office .She didn't send the email till now and the time is 14:38.wheni called again was told she was on lunch and when they tried calling her she argued with me and was very rude. The lady at reception ended up handling the call. This is a joke as I should have received my monies. I trust this brand that's y even my family retirement is with them. This is the service I get? I'm in sales n have targets don't have time.
