Transport Advice - Cala Rajada to Palma to Cala Rajada

I want to do a day trip to Mallorca Centrr from Cala Rajada but I couldn’t find any suitable public transport as it takes almost 4 hrs with public transport.

Hence I started looking for taxis but I couldn’t gather any credible info. Can you please advise on how can I travel to Palma Center? On 25th April.

Thanks
