I requested a copy of my invoice on the 21-05-2015 , I've spoken to Zeenath who was immediately very rude and arrogant.I then requested my daughter in law to contact the office and she was advised that the billing is not done and she will have to speak to Sindy.Sindy was contacted and they advised that it will be done and then only will Zeenath be able to provide the invoice, and I must contact them on Friday I gave them some time and called on Monday, I spoke to someone that answered who advised Zeenath not available and must call at 3, when I did she was rude and made statements \we are doing g ***** and she was screaming and she said hold on I want to record this conversation
