failed delivery

Good Day,

I am very disappointed by the service or lack there off. I was expected to receive a parcel yesterday but the delivery failed. At about 3pm, an sms came stating the driver was on enroute. Upon inspection of the TRACKING LINK, it states the 'unable to deliver your parcel to you' - High Risk. This is purely unacceptable. If we are unable to do deliveries, please contact the customer and inform them. I am not sure how do I even get my parcel. How do we correct this? (CDM***)
