CELLC "REPAIRS" MY PHONE FOR MORE THAN 3 MONTHS NOW

I took my cellphone in for repairs at Cellc, on the 5th December 2021. It is now more then three months later. The cellphone only has a cracked screen, but apparently Cellc don't have the spares for the repairs. When I booked my phone in, the agreed term was 14 to 21 workdays, therefore to me three months is unacceptable. I even requested that my phone get send back without being repaired, after already paying my excess, this also hasn't been done.

In the meantime I am still paying for this phone and the insurance on it. How can a Cellphone company not have cellphone screens and takes more than three months to get it? I am really frustrated at this point. I phoned several times, spend hours on the phone with Customer Care, still no luck.
