Shopify Integration Problem With Bangladeshi Local Payment gateway Service Provider .

[MH8]

 I am about to purchase a Shopify plan to introduce my new online business also I am trying to integrate our local payment gateway service to Shopify to collect the online payment but our local gateway service provider in Bangladesh is saying that the newer version of Shopify is not compatible with any Bangladeshi payment gateway service provider. Thus they are not able to provide their gateway to any Shopify user in Bangladesh. 

Therefore, I am looking for a solution to use and integrate Shopify with the Bangladeshi Local Payment Gateway service provider. Looking for a kind response from the team Shopify so that I can stay with Shopify to continue my business. Anyone can help me with this fact?
