Superbalist delivery service

I am unhappy with the delivery service. Drivers do not use common courtesy to try and find the person they are delivering to. If delivering to an office place why not walk in and ask for the person who is to receive the parcel if they cannot reach them on the phone. I have had to follow up three times with no joy on an order placed 27 June. Instead I am told it has been escalated with no resolution, twice I gave an alternative contact number but it was not updated, today the consultant updated the contact but still no resolution!! Is this how Superbalist works now!?
