False Positve on Dis-Chem's Medic+ Pregnancy Test

After trying to fall pregnant for nearly a year; I bought one of Dis-Chem's Medic+ Pregnancy Test kits as a routine pregnancy test. The product comes as one digital unit with 3 pregnancy test strips that you can insert to test for pregnancy (3 times). After doing the urine test, the result showed as YES+ which indicates a positive pregnancy test. I then tried to use the other 2 test strips, but the digital monitor wasn't coming on anymore and both of the test strips gave me no result at all. We took it as me being pregnant, a lot of excitement etc. That night and the next day I proceeded to do 2 Clearblue pregnancy tests to confirm. Both these showed negative. I then took the test's box and slip back the Dis-Chem (Willowbridge) and at first they said that they don't refund this type of item, but after my explanations, they refunded me with a voucher. I also phoned the Dis-Chem customer careline and they said that they have not had an issue with this device yet, and thanks for bringing this under their attention and they apologise for the inconvenience caused. And that was it. A few days after that, my period arrived, and I had another Clearblue negative pregnancy test result. The days in between these tests were very emotional and confusing. It completely ruined my Christmas time. Dis-Chem needs to realise that this is a serious matter and that something like this can be devastating for many couples that might have struggled with fertility. I will be taking further action against them.
