All betamax services such as Voipcheap, Voipbuster, VoipDiscount, LowrateVoip were possibly down or facing issues due to recent fire at betamax premises. Some users had complained about Voipcheap, lowratevoip not crediting their accounts. It could be possible that the fire has completely taken down their billing/payment system. Im sure there are backups. And they are still the cheapest and am happy to use them. Hopefully they will learn something from their mistake and we could happily use them for more free voip calls in the years to come.
