$3000 repair bill

[Anthony Morrow]

So my property mgt company emailed me a estimate for repairs with pictures for the one piece shower and description was a hole in the shower wall and the only remedy is to replace the entire shower for $3000. No explanation as to why it cannot be patched and no explanation of how this damage was done. What recourse do I have? I asked for a second estimate and they said I will have to pay a quote charge for the original estimate.
