Worst Service Ever!!!

I have been trying to cancel my policy with old mutual since the 23rd of March. I received an email stating that the process takes between 7-15 working days. after weeks of back and forth email and i am still waiting for R549!!!!! to pay out, meaning if this was a policy for more than 100 000 payout i would have probably waited 3 months???? its the 16th of April and i am still waiting, I called the services centre and they cant give me an answer as to when this process will be completed and they cant give me a number for someone that can give me an answer. I am utterly disappointing in the service old mutual has to offer!!!
