I paid for a return ticket Heathrow to Paddington in the upcoming month and my credit charge has already been charged. I have done this many times before and have typically been sent a confirmation and barcode for the conductor whilst I've boarded.

This time I've received nothing and have inquired twice on the Heathrow Express website. They have to responded via e-mai for over 10 days. I've tried using the telephone contact number they gave me, but it does not work.

Am I using the right number? Anybody have a suggestion on the best way to call? The number Im using is 011 44 345 600 1515 (calling from USA)z. I just get a fast busy signal. Any advice is appreciated.

Thanks
