Citiq Prepaid's Service Sucks on another level

Shocking service. I have more than 20 Citiq prepaid meters in use. On 28 September I had a problem with a prepaid water meter - after troubleshooting which only entails pairing the meter with the interface although it is already paired - for 4 days and several hours on the phone I am told that I am being put through to Sales who can do advanced trouble shooting - NOT TRUE - Sales wants to sell you a new meter and does. On Wednesday 1 October Sandile tells me he will arrange a technician to assist the next day, once I have made payment. I send proof of payment within 1 hour or receiving the QUOTE not invoice, Next morning Thursday 2 October Sandile phones and says the technicians do not have replacement meters I need to wait till Monday 6th October. Monday has come and gone, nothing heard from Citiq - not even an acknowledgement of the proof of payment. Today I have left 3 messages for Sandile K to phone me back and sent an email, I have still not had the courtesy of a reply - when I phone to speak to Sandile K, I am told they cannot put the call through they need to take a message. In the meantime my tenant HAS NO WATER. AND NOT ONE AT CITIQ CARES BUT THEY HAVE MY MONEY
