Worst service!

It was the worst service ever. I tried to open an account with them for wifi. They said they would send my application and get back to me the following day, it's been 7 days and not a word from them. I drive all the way to the shop and tell me the person who helped me is not available and so they can't help me according to his mistakes. They then said we have an unsettled bill but we settled it 7 days ago and brought them the receipt. It was just a terrible experience where no one can really help me. Oh and you can't call them because they just don't answer.
