Worst service provider.

The filter warehouse was utterly unprofessional. We requested for quote on the 5th of May and it took 2 months to complete an exercise that could have been completed in 3 weeks. When complaints were raised against them outlining the issues, they didn't even bother to give a proper reply and in the end refused to accept my calls. They let me speak to the receptionist and gave her messages to pass on to me. As one company to another this is shocking and unacceptable. I will NEVER use them again and they have been added to a "not approved" supplier list.
