Olx India — Featured ad removed

I paid for featured ad 1650 rs . They placed my ad for 2 hours only and then they expired my ad however they took money for 30 days. Reason they told me that I changed the location however there application captured wrong location and I corrected it manually. Now they are saying they will not put my advertisement back on featured. For only two hours they charged 1650 rupees. I am very much disappointed by there features service. Please help me to resolve this issue.
