Terrible Service

I decided to do a Price lock for the new Explore Ultra In February with installation. I received confirmation this would take place on the 6/2/21, this did not happen and on contacting the installer was advised that they can’t install as they have not received the decoder from DSTV? I HAVE LOGGED QUERIES ON 8/2/21 12/2/21 AND 19/2/21 REFERANCES i129, I 133 & ***0 and have received sms massagers saying installation is taking place on 3/3/21 and then again on 5/3/21 but this has not happened. What does one need to do to get service??????,
