Renew-It Wynberg needs to Renew their professionalism and Ethics

Since coming into contact with this company, I have had nothing but endless problems and stories. To not having received the quote from the insurance company, to not having the parts, then the parts are there, the car is in the workshop, then I was told the insurance hasn't yet approved the new quote. When I called the insurance the quote was approved and sent through already. When I called the Manager, Callen she then told me the parts were there but they could not start until they received the go ahead from the insurance. When I contacted the Insurance company, they confirmed that the email was sent to an employee at Renew it. When we got that sorted, I then called Callen again and confirmed the approval was sent through. She then said they will now go ahead and order the parts. The very same parts that were supposedly there already. Whilst this is happening, I am requesting that Renew-it please send through an invoice in the meantime so that I can make part payment, as it will be easier for me financially, rather than part with the full amount for the excess. This was two months ago....... i only received the invoice today via whatsapp and then informed that payment must be made within 24hrs of notification. How do we not understand or have empathy with people and their financial situations in this country, or is it just business as usual. A living nightmare!!!! WILL NEVER USE THEM AGAIN!!!! RUDE AND UNPROFESSIONAL!!! Also FULL OF LIES!!!!
