Incompetence/Inconsiderate/Unprofessional?

BOSS PAVING JOHANNESBURG On 31st of January 2025, Brad visited the premises. I received the quotation on 3 February 2025. I paid the full amount. Received an email from Desiree (Informing me that the work will be done on 14th or 21st of February). NO further communication from BOSS paving. I phoned, and Desiree apologized for lack of communication and for not informing me of the date. TODAY is the 20th and I ONCE again had to phone. I was informed that I should have known that they will not be able to do the work (raining). My question: Is it incompetence/no consideration/unprofessional? Surely, you inform clients about delays/rescheduling?
