Bad service and lies from Hisense

On the 8th of December, we logged a call with Hisense for a damaged TV, ticket number *** The technician came on the 19th of December, 10 days after a call was logged. When the TV was collected, technician advised that on Friday, 22 December he will try to get it back to us. Thursday, 21 December we called Hisense, promises were made that the TV will be delivered on that day, in fact we were informed that the tech is on his way with our TV. We waited and no one came. Friday, 22 December, we called again, once again promises were made and were given the "technician" number who's suppose to deliver the TV. We called the number only for the number to go to the service center, where we were informed that the TV is still with them, and it will only be delivered on the 28th of December. Today, the 28th we called to check what time will delivery be done, only to be told that the service center is closed until the 4th of January. 1. Why were we **** to with regards to (a) turn around time (b) delivery on the 21st and the 22nd, to a point that we were made fools of and were given a "technician number", while they knew fully well that there's no technician who will be delivering the TV (c) the date of the 28th, again, why make a commitment that on the 28th the TV will be delivered, knowing fully well that the service center will be closed. These are some of the people we spoke to, Ntombi, Sanekelisiwe. It's been 20 days dealing with Hisense and being **** to
