Unsatisfactory service

Hello Peter... I go by the name of Ms Khanyile Molekwa. Last year i made a credit purchase of a 49" HISENSE flat screen tv from the lewis store branch in Paul kruger Street Pretoria which was for my parents, back home its just my mother and my father staying alone and around Dec my dad noticed that the tv had blue lines running across the screen so him being a radio and tv technician brought this to my attention and i told him not to do anything as i had been consistently getting sms's notifying me about the two year warranty that the tv came with so i went to the nearest branch and i was told to make a complaint at the branch because they did not have my details on their system. So i went back to Pretoria and reported it and that was when i was told to take the tv to my nearest branch mid January 2018 the tv was sent to the witbank branch because that was our closest branch but the tv still sat there a month they said they waiting for a technician from Pretoria to come and collect it because they said they didnt have the paper work so then tv went back home still not fixed in march i made means to bring the tv to the Pretoria where they were told the tv had been fixed and it wasnt ...a lady by the name of Kokets laid the complaint for me but was not doing any follow up until she left the branch to go work else where and in May Thandi the store manager took over and promised to make a follow up, at some point she mentioned that she took the tv to the technician in Pretoria west so that they could review whether or not the tv could be fixed or i needed a new one this was around June ive been in contact with Thandi and every time she tells me shes on it or she will get back to me and that shes busy with an interview i last spoke to her yesterday the 29th August and her words were that she would call me back shes busy with an interview ive been very patient with this process and i believe i did allow enough time for them to do whats right but i believe for a good paying customer the service I've been given is truly unacceptable i cant keep going to the branch and evrytime i dont get follow up because the people they calling are on lunch or off ! im paying a lot not only to keep going to the branch and calling but for the tv as well and its heartening that im almost done with the purchase and ive been given such appalling service ...your help will be greatly appreciated

Thank you in advance Ms Molekwa
