Bad customer service

We purchased a TV at Incredible Connection(Maponya mall) and a year later, TV is not working. We then took the TV back to Incredible Connection(Maponya mall) and were told that they will log a call with the supply and let us know the out come. yesterday got a call from Kelvin from the store and told us that the suppliers discontinued the TV so we must come to the shop to choose another TV. We went today at 9:00 and they said they don't have the TV for same price as the other one and we were advised to choose any TV if there's a difference then they will give us voucher so that we can take anything for the price difference. we then decided to take another TV and there was a difference and for the difference we chose to take a soundbar. we stood for 2 and half hours waiting for them to process the transaction. then we were told they don't know how to remove the soundbar and the TV off the system because of the new regulations and now we need to order online but our question is that we are not buying a TV. we are getting a replacement?? when they phoned us yesterday they didn't say anything about their new regulation, they said we must come take a TV and that there wont be any problems because this is a replacement and the supply instructed them to do so .we spent 3 hours at shop until they told us that they will check which TV they can give for the same price as the old one....They should have told us yesterday that they will call when they have a TV (same value ) available for us. not to waist our ****** time for nothing!! and no one even apologized for all the inconvenience caused and miss communication on their end, not even the manager!!
