Absolutely rubbish. It's keep happening. I live in quite a big Victorian house and you'll never hear a tap on the door of youre in one of the rooms towards the end of the property. For this very reason, I've had a Ring doorbell installed. That way, when the doorbell rings, it sounds in every room thought-out the house on all Alexa devices, do that any important parcels get collected etc. The delivery guys rarely use the doorbell but simply tap the door. Guess what? I don't hear it. Then they go away. This happened today with a very important parcels and one which I paid extra for a quicker delivery. Then when you try to call the customer services phone number, you are only greeted and assisted my an automated response. Is this the best customer services you have DPD Local? What a joke.
