shocking Samsung

i write this experience out of exasperation.I replaced my galaxy flip 6 screen protector on June 18th.this was done at SSS Cellular in Edward street,Bellville.my device was still under the supposed Samsung 24 month warranty but was told i was liable for the cost as it was not covered under this.Bear in mind this is R30000 phone.I proceeded to do it.8 weeks later the brand new screen protector has failed again.this after i just spent R600 replacing it.now SSS cellular says they cant do anything as Samsung will not look at my case..8 weeks..it is disgusting.I am uphauled at the service from Samsung and SSS cellular.this treatment towards a Samsung client of almost 20 years.
