Yeah, that may be the issue because you certainly should be seeing things happening 4 weeks in... After 2 weeks you should start feeling and seeing things.. That is not the most reputable company and unfortunately, that is likely the issue... IO try to not throw stones etc but when it comes to this, there are far too many companies that have bad reputations and that certainly is one i have had many guys in the UK complain to me about... There is not great options out there for you unfortunately but id say at least 95% that it is your quality or lack there of
