Poor customer service

I visited Sounds Great, Clearwater Mall this morning to purchase a new TV, my TV licence in hand. I pay my TV licence by debit order on a monthly basis for many years now, but I was informed that my licence shows an outstanding balance of R224. I tried to explain to both sales persons that the balance reduces every month by R28 and that by October 2018 the full amount is paid. Neither of them would budge and refused to accept my licence a valid licence. I then visited the Samsung shop in Clearwater Mall and they were very helpful. The contacted the SABC and in a few minutes the problem was solved and I was able to purchase a TV. Both Sounds Great and Incredible Connection needs to take a view pointers from the Samsung staff about customer service. If they just put in a little more effort, like the staff at Samsung, they might not have lost a sale today. Very, very poor service from both of them.
