Disgraceful **** Artists - CarFlexi.com

I was charged over R1500 from carflexi and I dont know why? It wasn't taken off of the original invoice so we ended up paying a lot more than what was quoted. Someone should please contact me with regards to the money - I am not happy with this service at all. Confirmation number is CFADC666. Lodged a complaint on 11 April and no one has contacted me. Absolutely unacceptable. Biggest **** artists ever. Where is the refund??
