Service is horrible at Renault the Glen

Horrible Service. Bad decisions that inconvenience the customer. I bought a Renault Kwid Climber 2019 in March from Renault The Glen. Online it promised a free 2 year service plan that’s why I got it. I was told by Ntombi(sales person) that my car definitely has that service plan. I went again to Renault to get my number plates and was told I don’t have the service plan and I confronted my sales lady and she said not to worry I do have the service plan. When my car was due for service I went there and my car was given to me later that day and it wasn’t serviced. Ntombi then apologized for the inconvenience and promised me a discount on the service, I had to pay R1500. How because I didn’t budget for a “free” service. I then decided to escalate this and sent an email to Ntombi and all she rep**** with is “I’m waiting for head office”. This is totally unacceptable. Why promise something that you can’t fulfill? All they help me with is “sorry”. She didn’t even show sympathy when she rep**** to my email. The only thing I hear is “sorry , you didn’t sign for it” how do I sign a document that isn’t issued to me? Who says no to a free service plan? They claim that I said I don’t need it, and reminded me that if I surpass 15000km before service I’ll forfeit my warranty. I’m really not impressed
