does anyone experienced problems with Bitpanda's support?
I've sent some money on my EURO Wallet there and they did not arrive. I reported the issue to the support and no one cared to answer for the last 3 days... Perhaps it's a sign to look for another exchange?

Please understand that we are currently seeing an incredible amount of traffic on our website, the support demand also goes up in the same amount. So currently the waiting time is a bit more than 3 days. We are doing our best to get faster answers.
Regards
I do understand. However, please understand that keeping people waiting for more than 3 days for a support answer (which is not yet a not problem solution) puts you in a very bad place when it comes to customer reputation. And do note, your prices are not the cheapest around (which would then make it quite understandable for people to wait that long to receive service). At least a proper announcement in your official channels would be nice.
Don't you think with the current drastic spikes in demand it's not really possible for any service to keep up? In regards to human ressources you always have a very slow adaption to the demand. You have to find qualified people and train them. You can't really just buy some more capabilities on demand, like with servers, at least if you want to keep up QoS.
