Poor feedback and promise

I had placed an order on the 24th, scheduled to be delivered on the 28th. On the 27th I received an sms stating that the parcel would arrive before 5pm on that day. Confused , as I wasn't present at work that day I called the client concierge. There I was assisted by Hughlynne Anthony, whom informed me that she would communicate with the courier and I would receive my package tomorrow as promised. She informed me that she would call me as soon as she got in contact with the courier. No calls whatsoever, the courier arrives and marks my parcel as a failed delivery. Thereafter I get an email saying that I will receive it tomorrow as scheduled. After waiting throughout the day- I was a bit sceptical and decided to call client concierge again. The order didn't leave the batch , no communication was made. Hughlynne had failed to confirm or arrange the proper schedule. I am now receiving my parcel on the 29th . The service was very poor , with no follow ups being done or feedback. I am not upset about late delivery, but lack of communication and efficacy. Why do you ask your customers to choose a delivery date that suits them if your service cannot keep to it ? Very unhappy with my first experience ! I recommend you choose the day before or after the date you actually want , because that is currently the delivery trend
