Bad service from Suzuki Montana

<p>I sent my car for 90000km service to Suzuki montana, there was a belt that was supposed to be changed during service, belt was not replaced due unavailability of spares. I was told that as soon as belt has arrived they give me a call. My car is currently at 96000km and I still have not received a call from Suzuki montana, I called Suzuki on friday 24 March 2017 to enquire. I was told by consultant that they will give me a call after checking what was going on. I called again today asking to speak to principal manager, apparently Principal Manager is not available and no one is able to help me.</p>
