MTN and Samsung poor customer service!

I sent my phone S8+ back on the 2nd of Jan 2019, for repairs till today the 22nd Feb i have been getting the run around and noone bothers to update on the status! First off the phone is supposed to be water resistant for 30mins under 1.5m water with no issues, mine wasn't even under water for that long but lo and behold it glitches shows a green screen and switches off. When i followed up the first time turns out they were sitting on it because they sent an email with a quote that they wanted me to pay so they can fix the phone! This despite all their adverts of people jumping in pools with the phone etc. I disputed this quote stating the facts they falsely present on their ads then they decided to put it back under warranty and fix it, promise was that it would be done by Fri 15th Feb 2019 and ready for pick up. I follow up today and seems they are only fixing it today and will "hopefully " be done by Monday...which i sincerely doubt! Its been 2 months and i am paying for this product yet I'm not using it for 2 months!! MTN simply gives all the blame to Samsung and has us do our own follow up despite the fact that we purchased the phone through them! Below is the track of the people and days i contacted Samsung with no effect.
