3 Weeks of waiting

I received a wrong order from Homechoice on the 29th of August, I might have probably selected a wrong mattress size. I called the call centre on the 31st to advise that I need them to come collect the mattress. I was informed by Nomgcobo that I will get a call from the warehouse to arrange pick-up. I called again on the 2nd of September doing a follow-up on this and spoke to Linda who had such a bad attitude and told me that I must wait for the call from the warehouse. I called on the 4th and spoke to Janine who told me that the request was done incorrectly and that she would do it again and I will have to wait 7 days from the day. I have been calling every second day since then until today 18/09/2015. I spoke to a very rude Nadeema who wanted me to listen to what she was telling me despite me telling her that I have been waiting since the 31st of August, it's been 18 days instead of 7 days. She informed that the request was only sent though on the 16th of September and I must just wait for the warehouse to call. She also made me speak to the TL named Maruwaan who advised me the same thing. This is delaying me from making payment as I need the correct installment to make payment.
