Really poor service

I had the worst experience today, Had 2 orders cancelled after waiting over an hour for each of them with no explanation to why they were cancelled, the one was cancelled by the delivery person which I don't understand and then the second just cancelled. Told funds were immediately released back to me but after asking I am told I might have to wait 10 business days for this to reflect, this is really poor service and I am beyond disappointed. Both these have left me no option to even try order again due to the time elapsed and no answer as to why exactly both these orders went this way
