Shocking service by Huawei and partners

We bought 2 Huawei Band 6 watches from Sportsman's Warehouse in Tokai in April this year. These were recommended by Sportsman's warehouse as these are watches recommended by Discovery Vitality in order to get points for exercising- we needed these for swimming(indoor) and cycling. We were told that these watches are ideal for this purpose. We paid in excess of R3 000. We both noticed that our heart rates were incredibly high(according to the watches), but believed it would settle down. My wife swims 6 days per week at Virgin Active and I do about 3 times per week. We noticed after a few weeks that: a) the heart rate monitors were showing incredibly high heart rates, which were totally wrong- we both measured our rates on other devices- completely incorrect. b) we were not getting any points allocated for our swimming, which is the main reason for purchasing them. c) we contacted Discovery, after lengthy discussions with them, we discovered to our dismay, that these watches do not sync with Discovery vitality and therefore we would not be allocated points, but there was a workaround, where we manually took screenshots and then attach these to an email and send to discovery. d) were told by discovery that this was a huawei issue but they were working on it. e) we went back to Sportsman's warehouse, told them our problem, they said not their problem, these watches were recommended by discovery and that we need to take them to huawei in canal walk- the other side of Cape Town, at our expense. f) we then phoned huawei- firstly they were rude and arrogant on the phone, but they promised that a manager would phone us, needless to say, no one did. We phoned again a few days later, told that a manager( of which there are many)- their words, would phone back. Guess what?? no phone call. We phoned a 3rd time- again promised they would get a manager to phone. We are still waiting for someone to phone us. They then asked us to complete a survey- we did this- they received a poor rating and thought perhaps that might elicit an answer or phone call. Absolutely nothing. The service from Huawei is appalling, non existent, we want these watches replaced with ones that actually work, sync with discovery and as a result allow us to get points. We have been fobbed off by all the parties, we are feeling we purchased goods that do not work and no one seems to care. Hopefully this will get some action.
