Account not reflecting desposits

More and more often, I transfer money from my account to theirs, and after waiting for half and hour as they state, I see no money arrive in my account, which means I have to keep contacting support and give them proof of payment so they can manually allocate the funds. Just when you need the money most, I don't have it because VCpay top up failed once more.

Not content to take a percentage off of the money deposited, now it seems like they've taken to taking the lot. Something's fishy here. Either Zazoo fixes this problem or an investigation into the company should be launched.
