I recently returned from Vietnam and the airline at the airport in Vietnam issue the badge at the gate. When I arrived in Heathrow there is a part in the buggy broken. After complaining at the airport I got a report and then I contacted the airline who said they gave me a tag in Vietnam that release them from compensating for any damage. I understood others airlines compensate/fix if they damage a baby buggy. I don't know what to do now as if I contact my travel insurance as the part is £80 and my excess is £50 I have to pay most of it. Is there any one else to complain about the behaviour of the airline?

Most other airlines in the world offering carriage on an international ticket would be bound by the Montréal Convention, which would make them strictly liable for damage caused to checked baggage while it is in their care. The Convention also makes it very easy to bring claims against a foreign carrier in your home country, either as the passenger or as the passenger's insurer (through subrogation). In the UK you can actually bring a claim online for a few pounds.
Unfortunately, Vietnam is not a signatory to the Convention.
Vietnam has set up a parallel legal structure that, in the places concerned with airline liability, largely resembles the Convention, but it is a foreign law while you are in the UK, and for an £80 claim, it is not going to be sensible to raise a dispute.

The only positive thing I can say, is that it seems under Article 167 of Vietnam's Civil Aviation Law, such a "tag" is null and void.
Art. 137 (1) Any agreement by the carrier with the passenger, the consignor and consignee on exoneration of the limits of liability referred to in paragraph 1 of Article 166 shall be null and void.
You can try writing back to their complaints department, but I think to be honest you are not going to get your £80 back. Your best bet is to discuss the matter with your insurer, or possibly raise a Twitter storm.
