Takealot cannot keep their word

I ordered a parcel and was promised delivery by 23 December 2015. It arrived on the 22nd December but it was the incorrect order (A bunch of Micro SD Memory Cards). I didn't accept the order and sent it back with the courier. They promised the correct items will be delivered on 23 December 2015 which was my original delivery date. At 15:24 on the 23rd December I received an e-mail stating that my order has been delivered but I did not receive anything. I phoned the callcentre and they adviced it was rescheduled for the morning of the 24th December 2015. When I phoned them on the 24th December 2015 they said delivery will not take placed anymore. This is unacceptable. I will NEVER use them again. Just when I thought I found a trustworthy online store they proved to be just as the rest. You will not get any support from me or family members and friends again.
