Incorrect Billing and Bad customer service

Mike from Cartime Richards Bay replaced wiper blades on my car and did not inform me prior to doing so, which ended up costing me R 440 for the wiper blades and R 195 for the labour. Those particular blades do not even work well.When I informed the Richard's Bay branch of this discrepancy, the manager Mike told me that their head office said that they can only give me new wiper blades, but they will not correct their mistake. I explained how I had not agreed to that, so they said I had and that they can not reimburse me.On the 14th of April 2016 my daughter called their head office in Durban on my behalf and spoke to Justin who was extremely rude, but said he would investigate and get back to me by Monday the 18th of April 2016. However he didn't and she has to call them back again today, which is the 19th of April 2016. This clearly showed that they did not care about my particular case, seeing as everytime we spoke to him, he spoke down at my daughter in a rude and ****** and condescending manner. He has no sense of customer service, he and Mike the Manager from Richard's Bay are rude and very ******. <br>
