Incomplete because after 4 months still not received the 4th coin in collection at 1x coin per month......but they told me that the limited edition 5th proof coin must be ordered now due to low availability at £400.....I told them I will not start paying for it until I had received the 4th coin. I was told this would be fine, but after 4 months still not received 4th coin and yet keep getting demands for payment for the 5th coin. I phoned them in November 2017, and although they are very hard to get in contact with by phone finally got to speak to someone, I was told sorry and yes ignore demand letter as it was sent out by computer. December received another demand so tried to phone them on the 6th dec........but you get held in a very long queue...after a while a message comes up saying "we are very sorry but due to high busy calls we are unable to answer but leave your Number and a Agent will get back to you" Know one got back to me. Phoned back on 15th Dec and after a long wait finally got through to someone and had to explain the whole issue again.....was told by a Kyle that he was sorry and would send the 4th coin to the collection and the cert I was missing from the 3rd coin the next morning. Weeks later still nothing. So tried to phone twice more in January 2018 to wait then to hear the same we will ring you back message....but yet again both times no phone call back. Phoned yet again on the 2nd Feb, twice on 5th Feb....finally got through to someone after yet another long wait....by this time I was so angry I told him that I wanted a returns label and return the partial collection as I had had enough.....the gentlemen told me he did not have the authority to send returns label as this had to be the manager, but yes you guessed it the Manager was not there until tomorrow. I was told that a PM evening phonecall would be made to me by the Manager for a chat about my issue....I said to the man "well, will he definitely phone me because you lot are not very reliable at phoning customers back" yes definitely was the answer. But yet again, was let down and no phone call. I have since tried to contact London Mint again at 15.38pm on 8th Feb and again at 17.22pm on 8th but got the same lying bullchit message after a long time holding the line in a queue to we are busy please leave your number and a Agent will get back to you.....we yes you guessed correct again....No one phoned me back. I had this same trouble 6 years ago and dumped my membership because of all the hassle and poor lack of customer care.....cant believe I decided to give them another chance. It certainly is the worse company I have come into contact with (or should I say lack or contact...excuse the Pun) Would certainly not recommend anyone have anything to do with London Mint.....oh and by the way, the payment line you can get straight through to with NO problems, that just about says it all.
