Struggled so much for delivery, number plate, after delivery service which was pathetic.
Fastag not working. Raised so many complaints, to sales person, but no step being taken. Please refund that amount to us since we had to get new fastag now.
Disgusting and pathetic service. Even no reply to mail written to so many people in your company.
