Refund pending after poor IV administration

I have paid for a package of IV from this establishment that went so wrong. From the first administration of the IV drop that was a bad experience. The second was acceptable and the third dose did not even happen as the nurse just bruised me in 3 places. After the request for a refund was initially refused and when I sent pictures of the bruising to my arm, Joey (Manager) finally agreed to make the payment of what was owed to me. It is a month almost and I keep chasing this refund (e-mails and phone call) with excuses that Doctor in charge will process but never does. This establishment is dodgy and not a place I will recommend. For now as a conclusion I will like to get what is due to me.
