GET LESS FOR MORE (R)

I have had a extended warranty and service plan with Innovation Group since I purchased my new car. December 2017 I saw that it would expire in January 2018 so I picked up the phone and requested it to be extended. Cant remember exactly what my words were but as both (warranty and service) were to expire my intention was to renew and extend both. Quickly I was informed that it has been extended and what the premium would be. Surprisingly enough the premium was almost R50 more expensive but I was happy that I was able to continue. Today, 19 April 2018 I take my car for its every 7500km service and to my surprise I am informed that I need to go pay for the service at the cashier??? ***?? What happened to my service plan??? To my surprise I was informed that ONLY the extended warranty on my vehicle was renewed and extended and NOT my service plan!! I am actually so cross but disappointed that the consultant who assisted me didn't inform me that the service plan also expired OR offered to renew the service plan too. Afterall she would be getting the commission for underwriting it... BUT NO I had to stand there with a red face and make a plan to pay for my own service. I have requested the telephonic conversation of that specific date which was 20 December 2017 but I have to wait 7 days BUT I HAD TO PAY IMMEDIATELY. I feel that the agent who helped me Keneilwe Monnakgoti should have informed me that the service plan too was to expire and I feel that she had to ask me if I was interested in continuing with it. But because I MADE THE FIRST CALL maybe she felt that I knew what I wanted therefore didn't offer. So pay more and get less??? Yes this will be the motto for Innovation Group - why ask? The customer should know.. I feel that Innovation Group must pay for slipping up and not renewing WHAT I HAD. R814.45 thank you!
