Poor customer service by the store manager

My son bought a Jvc Smart tv LT50n7105 @ Gem/fairs Schweizer-Reneke on credit in 2020/17/08 the tv started turning on but stucked on Jvc logo, we then took the tv back and it was repaired after a long run around by the manager, 4/5 days after the tv showed double pictures we again took it back it was on the 08/08/21 On 2022/02/20 we decided to settle the outstanding amount of R4018.71 at approximately 15:59:02 and I was given the receipt(8171) by the manager . During the second week of February 2022 after the tv was fully settled the tv started again showing double pictures I then phoned the store telling them about the problem , the manager said she will send someone to come and check it, indeed the person came and said he will give the report to the manager, after a day me and my son took the tv back to the store for repair. I then went to check on the progress of the tv , I was told the managers was on sick leave, surprisingly the tv was still on the ground in the shop n according to the store they repair in Vryburg 62x2km to and back to Schweizer. No clarity no feed back about the progress o the tv. Now I feel the store delays deliberately because my son's account is fully paid. Speak Out on SABC2 is in formed
