Sanlam bad customer service

I took out a personal loan from Sanlam which I thought was from Sanlam. But they use Direct Axis who is known for their poor customer service. I personally went to Sanlam to ask them to change my debit order. They gave me a form which I emailed in Dec back to Sanlam asked them to deal with Direct Axis. So now the debit order has not gone off my new account since Jan. I am overseas. I have sent so many emails to Sankam and Direct Axis asking them to URgENTLy contact me and re-sent the debit change form. Sanlam sends me emails back saying that I don't have a personal loan with them. Funny I get a statement from them for it. Direct Axis does not respond AT ALL to any of my emails even the one to request a settlement amount. So now I am most probably going to be blacklisted! I only have 6 payments left. Never skipped one in 4 years. And practically begging them to contact me. How frustrating!!!
