Schwing Stetter India — service support pune office

Our company is having 2 slm 4000 machines under the name of m/s venus buildtech india pvt ltd. Which are working in pune. Yesterday there was a mechanical fault in one of our machines. We contacted the company and they connected us to service support pune. As the vehicle was not under warranty so the representative of service support pune told us that there will be a service charge for a service engineer to visit and check. We agreed and also mentioned our case to service support representative to handle on priority as some urgent work is going on. Ms abhilasha ketan khopade the representative of service support pune sent us the quotation over email yesterday at 6 pm. We sent the payment details as well as the work order in the morning as there office was closed. We have called for 4-5 times and it’s been 4 hrs but there’s no reply from there side. Customers are being fooled out here. Is this the after sale service that schwing stetter has for their customers? Kindly look into it very seriously and pls change such employees if they don’t know how to respond back to their customers. Quotation payment details and work is being attached. Hoping for a quick action with better service.
