RCS Call center agents not doing their job properly.

Hi I have a problem with RCS and their call center agents, firstly they will make you stay on the line for hours and still not help you. Friday I went to Guess Shop in Sandton to do a card replacement, they asked for an ID copy singed three times And we sent it in the store, they told us they didn't get the e-mail, I went back to work after waiting for 3hour at the store, I sent the email again and they received it. The agent told me to go back to the store and tell them that I sent the email so that they can assist me, I went there today and we called RCS and they are telling me that they can't find my email, after waiting for a full 40 minutes. I'm not going back to the store again they must just send me my card I'm tired of useless agents that are wasting our time because they don't want to work, I'm even gonna post this on the social media to show them that RCS agents don't care about their clients..
