No payment,No reply, and outstanding surveys not auctioned for payment

I have been with Springvale for over 2 years now and the service has been great,getting paid in time and surveys finalised and ready for payment in just a few weeks.But recently they have been a nightmare,they don't reply to emails and whatsapp messages despite Bering online and updating statuses.I recently enquired about my outstanding balance and found out that most surveys that were completed last month are still not completed,they asked for my number to send my airtime only to wait 5 days again without getting it or getting a response,and this would be done same day normally.They were great now they are just like the rest and not worth it anymore...Stay away
