Failure to repair my TV

This is the second time I am writing a review about this TV issue with Game store.Since a woman named Patience sent me an email about logging a call and none has given me feedback,and this has gone for a month now without a TV at home.If they say that they have implemented a new system then how do they keep up with customers buying on credits?Just because I bought the TV cash at once off,they tell me that they cannot find me on the new database.This is unfair and poor business ethics.
