Made a couple of calls and in return I received a couple of calls. My order is under processing now and it will be dispatched in an hour or so.
So, for those who would buy Mikrotik or any products from Multilinkonline.com, please make a call to any of the numbers listed in their website. Your call would be transferred to the right person or you would know who is incharge of the online sales. So, call the person to get everything fixed. You may have to wait a bit for him / her to confirm the payment with the finance department. You'd get a call back, when everything is okay on their end. I got another call from their finance department asking gst number. Since I am still an individual, I said so.
