I would like to share my negative experience dealing with Parcel ABC hoping that this might help other people. On 06.12.21 I sent a parcel from Bulgaria to United Kingdom. I was advised, that all parcels being sent from/to non EU countries are obliged to pass the customs clearance and sometimes Receiver is being charged to pay customs duties. According to Parcel ABC the approximate customs charge can reach up to 35 GBP. I was asked to upload this amount 35 GBP to my e-wallet (My Balance when I created my account with ParcelABC) in advance, just to guarantee that all amounts due will be covered. I used UPC through Parcel ABC to deliver the parcel. There was problems with the delivery but it was delivered on 16.02.21. The amount on the invoice for the content of the parcel was €40. I sent a message to Parcel ABC customer service requesting the amount of £35 (for customs duties that I uploaded) to be paid back because I didn't owe any customs duties. I received the following message on 16.12.21: "Dear Customer, Please be advised, that usually it takes 21 working days to receive customs invoice after delivery. If no tax invoice will occur, we will refund your payment. Best regards, ParcelABC" On 21.12.21 I request more information regarding the payment of £35. I received the following message: "Hello, Thank you for your message. We should receive the invoice on 14th or 15th of January, Best regards. ParcelABC" On 20.01.22 I ( 6 days after the deadline) I hadn't received any money so I requested more information. I received the following message: "Hello, I sincerely apologize for the inconvenience caused. Your refund request was sent to a responsible person. Once we will receive the confirmation, we will contact you promptly. Best regards, ParcelABC" On 27.01.22 I requested more information. ParcelABC responded with the following message: "Hello, Please give us time, as we did not obtain the invoice from the provider and the accountancy says they may still issue one. We just need to wait for an invoice. In the worst case scenario, till the end of the month. We will not hold on to your money, if we have confirmation that they did not charge anything. Best regards," I waited until 07.02.22 and after not receiving any money I contacted ParcelABC again. They responded with the following message: "Thank you for your patience. I understand your frustration, however I am not able to speed anything up. We have not received the confirmation from the provider regarding the charges yet." I decided to follow the complaint procedure in order to get my money back. On 08.02.22 I sent a message asking ParcelABC to provide information about their complaint procedure. I haven't received any response from ParcelABC. I tried to phone them on +44 2037 6969 85 but there was no answer.
