Disappointing Customer Service

The level of service that I have received from Old Mutual is beyond poor. I have requested for my life cover policy to be increase since May 2020. The quotation expired , I then signed another quotation on the 31 August 2020 and had blood samples taken on the 6th September 2020(WHICH IS NOT A NICE EXPERIENCE) but still no feedback was given until the quotation expired once again. I then submitted another quotation on the 13th September , To date vi still have not received any feedback. This is so disappointing. How long does it take to increase amount on an existing policy? Please let me know if I should take my business elsewhere.
