Tempted by the promise of calls to my brother in NZ I foolishly signed up with 18185. Their website is quite impressive - but beware. I was unable to use the service at all and was unable to unsubscribe. When I tried to make just one call I was greeted by a long message saying that my account was blocked and that this was probably because I had outstanding bills with another service provider. Or a technical issue. I have no such outstanding bills, that's for sure - in fact I have never used a service like this before. The long verbal msg / spiel went on to say that I could contact customer services on the email address on their website to resolve this. However, having searched the website there is no email address. Fed up I tried to unsubscribe but was unable to do so. The message thst popped up said thst I couldn't unsubscribe without paying my bill. What bill? As a precaution I have been forced to cancel the payment card I had to give them details of in order to sign up. I challenge anyone from 18185 reading this to come back to me via dooyoo initially to discuss - I am more than happy to do so, but their service wouldn't allow me to contact anyone! If I were you I wouldn't waste your time with this company - where is the customer service if things go wrong? All I have ended up doing is cancelling my card - just an inconvenience.
