Portuguese to English Marketing Marketing customer satisfaction survey from a gas supplier

Hi everyone,

I wold really appreciate it if someone could help me with this term.

It comes from a customer satisfaction survey for a gas supplier from Brazil to be translated into UK English.

The question asked was:

"Finally, do you have any additional comments to make regarding your experience with [company]?"

The full answer given was:

"Apenas lamentar que, em algumas oportunidades recebemos (Condomínio), cobrança e e-mails sendo que, o máximo que utilizamos é ""muito eventualmente"" adquirirmos um botijão para atender aos porteiros que utilizam o mínimo (esquentar marmita ou fazer café). Não compramos diretamente e sim de revendedores, colhendo apenas o recibo/nf daquela compra, portanto, NADA PODE SER FATURADO EM NOME DO CONDOMÍNIO, já que exerço a função de sindica há quatro anos. Portanto, qualquer venda em nome do mesmo, está totalmente desamparada.

So far, I have written:

"I’m just sorry that, on some occasions, we (the condominium) have received invoices and emails, given that the maximum we use is “very occasionally” we get a cylinder to cater for the porters who use a minimum amount (heating lunch or making a coffee).
We do not buy directly but through resellers, just getting the receipt/invoice for that purchase, therefore, nothing can be billed in the name of the condominium, as I’ve been the condominium representative for four years.
Therefore, any sale in the name of the condominium is totally desamparada".

I have found it mean "abandoned" or "unsupported" but these don't seem to make sense in the context.

Any help is greatly appreciated as always.

Kind regards,

Kerryann
