Poor service

I opened my account on the 28 June 2017,after it was accepted I never received my card and my surname was spelled incorrectly. I requested them to correct my surname and I was given a piece of paper written my account number and I was told to use it every time I wanna purchase or pay my account. Whats funny is that when I go to the store and try to purchase something with that piece of paper, I got stories but when I pay it was easy. I never received any call from Woolworths instead I am the one who was busy making follow ups since June. Every time I was told to come after 7 days with no luck. I only received my card yesterday (2018/02/14) and guess what? My surname was never corrected still. I am so disappointed, I never thought I will get such service from woolworths. That was woolworth Maponya Mall.
