Cauvery Indane Agency — repeat cancellation of order after generating invoice

Address:

KR Puram, Bangalore

Sir, we booked our indane cylinder refill online on 23rd march gas booking no[protected], invoice generated on 26th march no[protected]. It was cancelled by the dealer on 26th. When i called the dealer, they asked us to book again. I booked again on 30th march ref no[protected] on 30th march. On 31st march at 9.53am received sms that it is cancelled due to returned thrice. 2nd april received sms - invoice no[protected] is generated. On calling the dealer, they said your invoice is generated. We will deliver. Since 8th april, they have stopped receiving calls and there is no sign of delivery. This morning we received sms for refund as well. What should we do?
