Firstly, I would say that official resellers will be trying to have only POSITIVE reviews. This is for the simple reason - building trust and good reputation to attract clientele. Therefore, if you have reasonable claim- the reseller would go ahead with the refund without making any issues.
As you might have noticed, resellers are active on "social media"- Facebook, Instagram, ( again, to marketing and promotion to the potential customers) and they are very easy to contact to- there will be always Whatsup contact, Email or Live chat. Look below:

After Automatic answer, in like 5-8 minutes I received a message from the "staff member"

So I would say it was pretty quick reaction. Now, you might not get an answer straight away because: zone timing issues, out of work hours etc. But I am sure that any reseller would answer to your query promptly or would leave "out of office" remark/answer. Please note that depending on your bank it might take longer than 1-2 days- as I was dealing with refunds in past- official answer is usually 5-7 working days, in some banks might happen it is 14 days.
In situation where you would actually still had issues with the transaction- firstly I would dispute charges on my card. The company is being emailed/faxed with disputed charges claim and has 7-14 days for official reply. If they do not reply- charges are refunded to you automatically. If they are not able to give with the proof that they have provided the service- same scenario- refund is provided to you.
Now, If you feel you being scammed, you are encourage to report it to Cipsoft. They will not fight back for your refund as such- but they will keep an eye for the similar reports from other players. In case there would be multiple reports of reseller doing shady business- I believe they would remove it from the official reseller (and they could lose they discount on Tibia coins).
