Over piced service inflation 237% hidden agendas

I have reported this previously on hello Peter and was told as supplier response head office will query and contact me but unfortunately I have been querying this issue from the 13 Feb 2015 and today is 05 March and nobody have contacted me with regards to overpriced vehicle service which was inflated in price 237%! No response from supplier shows poor service delivery. Reported it to Bidvest customer number 5216 and still no response from head office Renault SA or Bidvest! Horrible service delivery! people must consider buying into this brand as no customer service you will receive as it evidence from 13 Feb till now 5 March 2015! I want somebody from head office to contact me with regards to over priced services and original delivery cost as invoices does not give true reflection of what has been done and paid for!
