Disaster hell service

On the 12 October I booked my car (Polo 1.4 comfortline) in for service at VW Arcadia for normal service, when I left my car at the service centre it had no problems whatsoever and waited the whole day to be called as they normally to do to tell me what needs servicing or replacement in my car, & I was not called to collect my car and it was around 17:00 when I called & asked when are they are going to call me to collect my car, the service advisor came and fetched me and we went to collect my car. When we get to the centre he went at back to collect my car where it was being serviced and told me to replace the brakes and dics. I get to my car he tells me that I must check my clutch because later it might give problems later. I went home the following day my car starts giving me problems- is now difficult to change gears. On Monday I took it back and my service advisor gets into my car and dismissed me very quickly without properly looking at my car saying I must replace the clutch kit and my car never had clutch problems at all when I dropped it for service. I emailed the Service Manager and he also didn't help me said I must replace the clutch kit that's all without investigation and "I can escalate my case with VW South Africa if I want"!. Now I am stuck using public transport to work.
