Im so dissapointed on the service we received from Defy after paying them

i recently contacted Defy regarding my fridge which was only freezing on the one side of the deep freezer & the other side was just cold. the top part of the freezer was not cooling at all. i called the call centre to get assistance and a guy came to check. he then told me that the fault will need to be fixed at the workshop and he will log a call. 1st week of Jan Defy guys came to collect the fridge and my friedge has been at the workshop for close to a month. last week monday 29 Jan, we called Defy and was told that the fridge has been fixed and defy is testing it to ensure that all is well. the fridge was tested for 4 days and on Friday 2 Feb, the fridge was delivered around 15:00. a fee of R2600 was paid to the defy guys. we switched on the fridge and left it on all through out while testing to see if its working. saterday morning i then open the freeser & found the fridge still in the same condition as before it left the house. is this the kind of service we paying for. you took my fridge for a month and charged me closed to R3000 for nothing. i demand someone to come fetch the fridge and fix it since i had paid and please ensure that you sent people who are not gonna complain about how heavy the fridge is as this is one of the challenges weve experience as your drivers compaint when they came to fetch and also when they brought the fridge. my fridge is still heating up on one deep freezer and the top side is a heater. my contact is ********** 769 or ********** 828. customer is Paul Kigonya
