They screwed up my scooter and paid 4192rs. Review on Gobumpr

Today I have provided my scooter service, without checking any reviews online. I totally made wrong choice. They took my bike around 10 AM and the rider asked me to come 1.5km from my home location, I still went and picked up him and provided the bike. After the bike was taken to service center, they gave me some quotation of 4500rs. even though the air filter was changed 3 months before, they still said it need to be changed, and when I asked can you send me picture of the current air filter in the scooter, they said, it yet to be opened, so before even checking the scooter parts, they gave me a quotation of 4500rs and finally they demanded all the parts need to be replaced else bike would stop somewhere, I was using this bike without any issue since it is 3 months from my previous service, so thought to give for general service, now they said it has to be replaced, I still proceeded with all suggested spares, I thought at least I will get my scooter in good condition. As soon as I received the scooter, I couldn't able to move the scooter itself, the reason the brakes were too tight and it was not allowing me to move itself, when I asked the delivery person, he said yes its not working.

Will anyone expect this kind of answer from when the scooter is serviced and it cannot even move? Though they have changed both front and back brake shoes as per their invoice. I got frustrated and asked them to repair and come, meanwhile, the person started asking for money so he can leave from here, I denied paying it without scooter function, I cannot make any payment, then he took the scooter again he said he will come in 1 hour, but he didn't come, I called him at 10.40 PM he said, he will come tomorrow, I worried a lot and asked him to fix the issue and handover the scooter, then he came in next 15mins and gave scooter, the scooter is still not functioning properly at it is already 11.15, I was more worried, that I might lose the vehicle if I give to them. later they asked me to pay and I still asked them why the petrol tank reduced by half, they mentioned they didn't take anything, maybe the rider took it, they don't have any picture when the received bike for service and they denied of the petrol issue.

Also, when I asked a cross question, why you ask to change the air filter initially, even though it was changed 3 months before, he told it got full of oil so he suggested that and he did replace now. but the truth is they didn't change that as per the invoice. So it is complete false info. now I am more scared of what else they have stolen from my bike. I tried to call GoBumpr multiple times today, when I had several issues, they were not available, and in the app, it was showing a different scooter image, and in the invoice, it has different customer name than mine. So now I am more worried, did they really change things for my scooter or someone else scooter, and they charged me 4192 just like that and stole my original parts instead along with a half tank of petrol. @GoBumpr, if you really care about your customer, please reply to me or call me on the registered mobile number. It is really the worst experience that I had in my life ever.
