Pathetic after sales service

1 stars because the product is OK. The battery DC cord does not make contact in the lighter socket. I exchanged for my other famous brand cable and the unit works well. One can see that the cable is faulty. I took photos of this and sent it to Flex. On 3 January after several comms on WhatsApp The people were very kind and promised to courier me a new cable. It never arrived. On 31 January I contacted them again. They gave me a story that their WhatsApp got upgraded and they needed my address again. Again it was supp**** and again no further communication from them. Empty pro.ises, makes one think how their repair serg8ce will be if needed some day. Pathetic.
