Bad Systems, No Communication and no customer satisfaction

I have several issue trying to purchase a new contract from the start of the week. I have logged several calls and emails with ZERO reply on any of them. Subsequently the prices of the contract I tried to purchase the whole week, increased yesterday. When calling the call centre again, I was told that the prices increased and I just have to pay the new tariff!! It is not my fault your website keeps crashing or keeps telling me the page is no longer available when trying to check out the item. The fact that I tried hourly for days with no success and then being told that I have to pay the increased rate due to you systems not working is beyond ridicules!!! For a company in the communication industry, they defiantly do not know how to apply it.
