big D I T T O on the last review and wish it existed prior to engaging with this company. I wouldn't have given any stars to this company if citysearch gave any other option. Computer Systems Integration, XDF LLC, owned and operated by Mr. John Makara... fails to pay employee wages on time. He'll lie to save a buck. This has resulted in a revolving-door for employees and poor quality service. Does anyone else find it interesting this company isn't listed on google or anywhere else that commonly accepts customer reviews ??? Mr. Makara has chosen to remove his company from these listings in a feeble attempt to protect the company from negative reviews. Buyer beware, if you can't find a company listed anywhere, its probably because they're hiding from critical review.
