Takealot from you!

So I've been a loyal customer of takealot for years now but I'm starting to lose my cool with this company. On 18th July I received my order to the value of R800. Used a gift voucher of R250 and paid the balance COD. the tattoo power supply your company is selling for R699 is absolute *******. To the untrained artist it would come across as a working device. Try doing a single line pass and see how the volts dip to the point where machine cuts out. I have 3 machines and all work perfectly on my backup power supply. On Monday 7 August my return was collected. I did everything as requested, however...it has now been 4 days and I have yet to receive an email or SMS from takealot on updates on my return AND my refund. I'm disappointed in the communication of takealot. I called in 4 times throughout the week with nobody giving me a direct answer and please stop using the taxi strike as an excuse for delays. Roads are much quieter so deliveries happen faster because I DID NOT have this issue with courier guy during the week they delivered on time and communicated with me regularly. I want my refund and my voucher to be recredited ASAP!!
