Hisense repair centre

Hi my name is Merilyn pukri i bought a 70" tv 1 year ago from hisense and it has 4 year warranty so the tv had sound with no picture so i followed the normal process by emailing all the documents and so on to the hisense repair centre and i did explain to vanitha that i have a baby who is downsyndrome whose admitted in hospital and went for open heart surgery so i need the tv back before he gets discharged as he can not be under stress cause he is attached to the tv she sent out 2 technicians whome came and viewed the tv and said they will come the next day or the following day to fetch it that was on a Wednesday so we made arrangements to be at home the Thursday and friday however nobody showed up on the Saturday morning a lady from the repair centre in durban north called me and told me they will come before 12 again i made arrangements and nobody came the following Tuesday 18th of june i phoned them and after them making me wait i was stern and told them i cannot make arrangements everyday and wait for them but nobody is coming so that evening the same 2 technicians came and picked the tv i did show them baby and that he has undergone major surgery to pls put it as urgent they said it will take about 72 hours.. I phoned everyday since then and all i got was rude service from vanitha everytime i spoke to her she tried to cut me off by saying bye merilyn have a good day which is totally unprofessional before i can even complete what i have to say or ask.. I had to phone each day for feedback cause they couldnt keep me updated as to what's happening on Friday the 28th of june i called again as i received an sms before i can even tell vanitha about the sms she cut me off again and told me she will phone the lab and call me back when she did call back she said the tv is repaired however theres no technicians and guys that are available to come and deliver the tv i did tell her that my son is under stress and is crying for the tv and he not supposed to be in that condition after surgery and if i can come and fecth it myself she said thats not allowed and that she will call me first thing on monday morning the 1st of july to tell me when they will deliver it half the day went and she never called so we called her and she was again rude, arrogant with no type of customer service or ways of talking at all.. I am taking this up cause i laid the complaint on the 11th of june tv was checked on the 12th of june picked up on the 18th of june and today is fhe 1st of july and theres still no help from this hisense team and repair centre its totally unacceptable and i want a full refund or a new tv as i cannot wait any longer and they also need to sort this type of employees out as we pay money for these appliances and when we have issues with it they must have people who know how to treat their customers.!!!!
