NON-EXISTENT CUSTOMER SERVICE!!! DISGUSTING SERVICE!!

DO NOT use this company! Their customer service is non-existent. I bought a mini UPS device through them - without realising IT - since I purchased the item through Takealot. The unit was faulty from the start and it is still under warranty. After a discussion on whatsapp (when they finally answered!) they advised to courier it for assessment. They admitted on whatsapp (once again after me trying to contact them numerous times) that they have received the item. This was 3 weeks ago and now they are not replying through any communciation channel!! Very off-sides!!! I would NEVER purchase through them again!!
