PC Link and Mustek is pathetic !!!!! - NO don't go there

Parthetic is all I can say. I ordered a ASUS mesh router from PC Link on 4 August 2020. It took more than a week to deliver from Randburg to Pretoria. Five days after receiving the router I informed PC Link that the one unit was faulty. A week later I complained that the balance of the system drops devices from the wifi network. PC Link collected the unit and 3 weeks later send the courier to fetch the other 2 units. A week later Mustek confirmed that their is a faulty unit and they need to repair it under warranty but they have strikes due to Industrial action. After 5 weeks I received the repaired system. I installed it and realised that it was still faulty. I informed PC Link of the situation and they told me to take the matter up with Mustek. For the past 3 weeks neither PC Link nor Mustek is responding to my emails nor are they sending a courier to collect their faulty piece of *******. If I want a refund there is a 30% service fee that will be deducted. There seems to be no marketing executive, director or MD to escalate complaints to despite my request for the contact details of a senior person to address this complaint. How is that for a rip-off
