Samsung buy&get ****

We bought a samsung wash and drier machine to the value of R9999.99 on the basis that we would receive a R4000.00 UBER voucher. We had other options but this was the deciding factor. Firstly to be able to send the first sms to redeem the voucher you need a pre paid phone. Never mind that the market of people who would buy a machine cash to this value all have contract phones. Then the endless process to try and upload a "PICTURE" of slips and serial numbers and then being told that its not "good enough". How can a proper serial number image and a Proof of Payment from the bank not be good enough. Who ever came up with the marketing campaign has made it nearly impossible for clients to redeem the voucher - i call that a ****. I am very disappointed in SAMSUNG as i always thought it was a great household brand. To top matters the machine is already faulty and its only been a month. So now apart from never getting the voucher we were promised when purchasing the machine we now have a faulty machine that needs a service and its only a month old!!! Cant get through to the call centers and no one calls back!
