AAA Diving was recommended but they have not returned my email from 2 days ago where I asked some questions and a quote for 8 full days of diving. Easy question I thought. Doesn't fare well for them at this point.
Just as a side note, sometimes things do delay answering emails and 2 days isn't a long time, really, even though I know we are all tuned to having super fast responses.
For example, our usual response time is less than 24 hours but can be up to 72ish, especially in peak season or very hectic times (we have an auto-responder that tells people this, too) and I try to give companies three-ish days to get back to me as I know I'm not their only enquiry and it all takes time.
See that you've found a company and that's great, just mentioning that maybe writing a company off after 48 hours is a little severe, assuming they really are trying their best!
