The customer service department is the worst. If you have a problem with your service good luck. We are a company who is hitting their busy time of the year and therefore we need more extensions to be active. I called on a Monday morning to have 2 extensions activated so our customers could call and we could make sales. I was told to email support and I was assured it would be taken care of that day. Well Monday passed, Tuesday passed and still nothing. Despite my follow up email on Tuesday. Into Wednesday, I called and explained it is very important we get these extensions active and could they just put me on hold and do it. They claimed they didn't get ANY of my emails. Keep in mind I emailed them from multiple accounts and from THEIR contact forms. I emailed AGAIN from the same accounts and on SUPPORT forms on their website. And surprise surprise it's the end of the day on Wednesday and nothing. Customer service is a joke. They do not care and now my company has gone almost the whole week without extensions we need.
IMPROCOM provides great and reliable service with perfect sound quality, price and customer service was very helpful. The technical support service was outstanding, they helped me with everything which I asked very quickly. I highly appreciate all the help, which was given to myself. The equipment system was great. Everything was heard very clearly throughout the call. The call did not drop even once, which is greatly appreciated, since these services have a tendency of doing that sometimes. I would be honored to give people referrals of you company. Thank you so much for all you help.
I have been with Alcazar Networks for termination and now origination and they have met or exceeded all expectations even in the one instance of minimal downtime in four years. Their support lines are always open, and their email responses are quick and easy to read (No Canned responses here). I migrated my traffic to Alacazar networks after reading many VOIP reviews, and their sterling reputation as a solid provider in the industry is what sold me. Upon switching over my termination, there was a instant cost savings especially when they turned me on to LRN routing. On top of that, crystal clear call quality and termination to more destinations I had not previously had which all in turn keeps my customers happy (More destinations, lower pricing). Alcazar Networks has helped my business grow over the years with their excellent and unprecedented service and commitment to customer satisfaction. I would recommend them to anyone looking for excellent Origination and Termination services.
