****ty delivery service

Disgusted by the service I received recently,made a purchase on Monday the 3rd of March and opted for a Wednesday day delivery because I knew they'll be someone at home to receive the package, late yesterday I see on the App that my delivery was scheduled for today, Waited but nothing came, only for me to get an sms that the delivery will be made tomorrow,, How do you give people delivery options if you going to deliver at your own time?How am I supposed to now make arrangements for someone to receive the package.The delivery service is disgustingly poor and very inconsiderate.Not Even an apology for the delay....VERY UNPROFESSIONAL
