Hi Robert I am sorry that you experienced this level of service from our delivery partners and we appreciate you bringing this to our attention. This is not the level of service we have come to expect from our delivery partners; I will raise this as a complaint with AIT, in order to prevent this type of issue from happening again in the future. Sorry again for any disappointment caused. Kind regards Charlie
