Russels furniture store

On the 05th of May I took my tv for repairs at Russels store in Rustenburg, even now I have not received any positive feedback from the store. When I and check if they have fixed my television, I am being taken from pillar post without getting proper assistance. If the tv cannot be repaired, why can't they give me a new one instead? This is totally unacceptable hence you always require your monthly installments on time, why can't you do the same when it comes to putting customers first?
