Refund issue - Consumer Complaint for GIGM.com God Is Good Motors- GIG Motors

I booked from Ikotun, Lagos branch to Utako, Abuja on 30/03/2021 and paid the sum amount of #14490, preferred seat no. 2. I was called on 31/03/2921 evening around 6pm by GIGM that I was the person that booked from Ikotun, Lagos to Utako, Abuja. I was rerouted to Akowonjo, Lagos branch. On getting there, I noticed that the ticket price at Akowonjo was #13,300. I made a request of refund from the #14490 I paid but GIGM could not refund my balance despite the inconvenient device I received.
I look forward getting positive response from you.
