Horrible Service

On the 1st of April I forwarded my surrender application with all my supporting documents in which they claim to have never receieved my attached id copy that was in the supporting documents. No one bothered to contact me to let me know only after several calls made to metropolitan. From the word go my cancellation pay out was R4300 in the recorded lines after numerous agents spoken too they gave me the above same figure yet today an amount of R3500 was paid into my account. What happened to the R800 I asked and they told me I opted for partial surrender in which that never came out from my mouth when I spoke to numerous agents. Metropolitan must pay in my difference as they told me it's their mistake and they need to reverse the money. Why reverse the money when you only need to pay the difference? If I got such service God forbid but what will I experience should there be death in my family? Please pay the difference as soon as possible.
