Unhappy client

I'd like to convey how unhappy I am with your service, I have a retirement annuity plan that matured on the 1 December 2015. I went to several branches where I was told that I should leave my details and a broker will contact me to discuss the payment because they don't deal with those plans, Iv been waiting for the call ever since then, today is the 20th of January and still nothing, this is my money and I feel I shouldn't have to beg or wait to access it. The system you use is pathetic and I will be advising all my family members and friends as well as colleagues not to do any business with you in future. I'm very disappointed and unhappy because iv been a very loyal client to old mutual ever since I started working and this the thank you I get, wow
