Pathetic service

I have sent a parcel, which was due to be a 24 hour service. Parcel has been sent on the 19th of October , 11 days has passed. Multiple calls between myself and your company , to date its been PROMISES,JUST PROMISES. How do you commit to a time frame and not keep it, when I checked your online portal this morning, it shows Attempted delivery last night @ 8 ??????, customer is not available... How was this customer not available, no missed calls on either my phone and the person who should have received the parcel. The service has been nothing but PATHETIC. very very disappointing service, I have heard about your service prior and now have first hand experience. I have requested a manager to call me back, not even this was done. How do you just disregard your clients like this.
