Disgraceful customer service!!

I recently purchased the funko pop Joker! Once again I have been sent the incorrect item by takealot. This is the forth time in recent months that they have done this, and with NO ownership of their errors!! I email them and all I get is a hundred and one excuses! I also bought it for R235 an they charged me R279 and would not refund me or admit they were wrong even though their website clearly says R235! Their customer service is a disgrace!!
