AluSteel Products - Shoddy workmanship

I asked AluSteel Products to enclose my balcony as I wanted to use this as a GYM during lockdown. They quoted and I paid them. They then delivered the wrong doors, I had requested frameless aluminium doors but they brought framed stacking doors. After a lot of back and forth as they claimed to be a small business and since the doors had already been manufactured they would incur losses. I eventually agreed for them to instal the ones they had brought. When the rains started the framed doors have been leaking. I asked them numerous times to come and fix but its still not fixed. Very very poor service and workmanship
