Anyone looking for Security, CCTV or Door accessories MUST be extra careful. Do not look for this company called ADDS Technologies Pte Ltd, they are located at Bukit Batok. This Company is providing a very lousy and bad service. The Service staff shouted at customer and The Managing Director of the company, only wanted to be known as Mr Chua without hearing from customer scolded the customer as well and use words and attack the customer personal. This is the worst company i have ever encountered, If you do not wish to end up looking around for help after sales, please do not go to this company. read full review »
