Takelot.com and their poor customer service

What poor service! Utterly disgusted by Takelot.com. I purchased a cell phone from them and found that it was not functioning properly. I requested for a return and opted for a replacement as they still had stock. I received an SMS stating that the exchange would take place on Friday 15 Feb by 5pm. Waited for them to deliver. Nothing. Made contact on several occasions and was advised by consultant Matthew that the courier was running late and that the exchange would still take place the same day! Nothing no courier pitched. Contacted them the next day and got the run around from everyone I spoke to. Eventually this exchange was rescheduled for today Monday 18 Feb. Nothing oncemore! Contacted Takealot to escalate and got the run around once again! No phone no nothing! Their Management to whom I escalated the matter still had not made contact with me! I waisted a whole day on Friday waiting for nothing! Today yet the same at my own expense ! This is most definitely the worst customer service ever! Empty promises. I will never make use of Takealot again!! They take your money easily yet when it comes down to assisting their customers they voluntarily take their own time! I spoke to a supervisor named Jesse and am still awaiting a call from her manager Karen! Epic fail!
