On [date] I ordered [number of tickets] from [name] at a cost of [£xx] which I paid using my [name] credit card.
The tickets [has/have not been delivered]. The full details of the problem are as follows: [describe]
I understand that under section 75 of the Consumer Credit Act 1974 you, as the credit card company involved in the transaction, are liable to the customer (me) for any breach of contract or misrepresentation along with the supplier of the goods and services.
The supplier’s failure [to deliver the tickets] is a breach of contract, and as I paid by credit card I hold you liable for this breach.
I therefore expect you to credit my account with the full purchase price of [£xx] within the next 14 days.
If I do not hear from you with a satisfactory response to this letter within 14 days then I will reserve my right to start legal action against you to recover my loss due to your failure to comply with S.75 of the Consumer Credit Act 1974.
As this is a formal letter I must refer you to the Practice Direction on Pre-Action Conduct and in particular to Paragraph 4 concerning the Courts powers to impose sanctions for failure to comply with the Practice Direction.
