POOR SERVICE FROM NETCARE REFUNDS

I received an email from clusterpatientrefund on 24 Nov saying that a refund was due to me and I am to submit documents before they can process the refund. I submitted the required documents on the same day and waited patiently for the refund. On 2 Dec, I sent an email to Zelnah whose signature was on the refund email and there was no response. I called the number that is on the signature, but there was no response. I tried to call them again on 9 Dec, but there is no answer. Poor service indeed.
