Hi fi corporation

I bought a 65 inch sansui tv 6 months ago, I visited hi fi Cornubia where I purchased the tv and they said they will send some one over, the company called ronniemastercare tv called me and made informed they would come on the 26/02/20, they did not come and called to reschedule for the 03/03/20 at 8:30, they came on the 3rd at 11:45, two guys one named SHANE, they were late, rudent, they told me they cannot take my tv off the bracket and I must get somebody to take the tv off the bracket and they will book another day to fetch the tv, I called customer care and spoke to Anita who was not helpful and told me, that I can take the tv to hi fi corporation on my own.
