Bad after sales service and deceiving representatives

My vehicle geaxbox got faulty and I had it towed to a workshop that was previously preferred by WBC. On follow up with the workshop I was informed the workshop (JAG Auto) and WBC were in contact and an arrangement to move the vehicle to a gearbox specialist was being arranged by WBC. I got an email confirmation from WBC (Shalin Daya) for this arrangement, but the vehicle was never moved to a gearbox specialist. Upon multiple follow ups via email with no response, I decided to follow up via phone call, the WBC representative denied the arrangement and the matter was escalated Karabo from WBC. After 2 days of not getting feedback, I called again and now the story changes to the call was closed due to outstanding information from my side at which I asked which information and they still can't tell me and still not getting feedback via emails. WBC also claims that they have tried to call me, at which I don't have any missed calls on my phone from them, and if they couldn't get hold of me via the phone why not reply on the emails I was sending weekly?
