Samsung sells faulty goods wrapped in sealed boxes...yet again

Samsung phones are yet again ************* for me. I purchased a new phone at Telkom Wonderboom Junction store in Pretoria end of March.The phone A12 has a speaker problem. When I took it in the technician told me that there's nothing wrong with the speaker. Knowing that I will be away for months travelling,I had no option but to purchase a phone that works.Well,at least that's what I thought when I purchased the A32 there. This A32 is ONLY a month old.I am now in the Gulf of Oman in a ship with a phone(new phone) that heats up,turns on and off by itself.Screen shows different colours of the rainbow. This phone is on contract but I can't use it.It's so frustrating to keep purchasing what should be a trusted brand but turns out to be a brand of fault and misery.

I will not rest until I get my refunds for both phones because either Samsung sells scarp phones or Telkom's storage of their phones isn't on par.Whatever the case is I am highly disappointed and dissatisfied.

All my electrical appliances are Samsung but goodness I won't be telling any friend to purchase anything Samsung
