I want nothing to do with old mutual anymore 😡😡😡😡

I changed my surname & submitted my documents stating confirmation of change from home affairs. I had a lapsed policy that even now I am still waiting for money. It's been 3 weeks now since I am waiting trying to call but the consultants keeps transferring my calls to one another. Now they send me emails that I cannot receive my money without married certificate. I am not married I only changed a surname for personal reasons. The staff of old mutual are not patient and eager to help not even friendly. I rate them 0 I just want them to fix their system & pay me money that I invested with them so I can leave them in peace. I am so disappointed because when they deducted money from my account they never noticed a changed surname but that I need my money surname is now a problem. Please help so I can help them to train their staff or rather hire people with knowledge.😡😡😡😡
