I phoned Govia on the 28 Dec 2015 to let them know I was travelling through their tolls. The lady told me she had created a 30day account and I gave her my credit card details for them to deduct the money. I was not home for few weeks. I got back later in the month and I got an invoice dated the 8 of January and was due 21 January. Unfortunately, I can't find my reference number but I have my phone records showing that I phoned Govia that date and billed me for. Now the bill has tripled and Govia is saying they can't find my account. I don't know what to do. Please help.
