Hi-Fi Corporation Southgate TERRIBLE service

I took my TV for repairs on the 30th August 2020. The repair department told me that they would provide me with feedback within 14 to 21 business days. I have called in a few times (might I add that the *** number is either always engaged or just continuously ringing). When I do get through I get told that my TV is still booked into repairs. I just called the Help Centre because once again I cannot get hold of HIFI Corp Southgate and they told me that my TV has only been booked in for 16 days. Now, HIFI Corp has had my TV in for repairs for 29 days (20 business days) and absolutely no proper feedback is provided to me and now it is in repairs for ONLY 16 days???? I have never seen such terrible service. Also, please do teach your customer care consultant some basic telephone etiquette!
