Tygervalley Branch does not care about MTN clients

I have taken out a Samsung contract at the Cape Gate branch. The experience was pleasant. However, the Samsung A32 is giving me problems. The reaction time on the screen is slow and sometimes stalls. I went back to the branch and I was advised to go to the Tygervalley branch, as it was my last day for the out of the box warranty and they had no stock. At the Tygervalley branch, they glanced over the phone and I informed them that my brand new practically empty memory, Samsung is sometimes as slow as my 4+ year old, second hand, full-memory, damaged screen Huawei. They, in their wonderful customer service expertise, decided that because it did not happen at that very moment, they will not honour the warranty. So now, I must book the phone in and wait for 7 days without a phone because the Samsung Rep and the MTN "customer service" consultant have decided that the whole of 1 minute they spent checking out the phone has deemed my issue non existent!
