Spree dishonest - i still dont have my April order they got wrong twice!!!

Hello, I ordered a pair of shoes on Spree 17.04.2018 and have yet to receive them. I initially ordered a pair of navy blue pumps. I received a pink pair of pumps and immediately phoned spree and spoke with Nomsa, the very same day they were delivered. She then apologised said she had changed the pair and that were going to be delivered shortly after the warehouse had checked them. I hadn't even taken the shoes out of the packaging, what's the use, they were pink. I then received another pair of pumps over a week later, after me following up on their whereabouts, and guess what, yip pink again. I literally spoke with the lady and it is still wrong. Spree then came to collect the incorrect items again. I have been asking since April telephonically and via email, almost daily for my order ********** 15 of navy pump shoes that I paid for. No one, not ********** nor ********** nor any other email address I could find have responded to me whatsoever. I used to shop regularly on spree when they were honest and efficient. I find them to be very unprofessional and will not shop with them again. I urge people out there to be very careful as they clearly are not interested in giving you orders you have paid for.
