Unable to allocate an apoinment

Nightmare from beginning to end. Call centre staff give mixed massages and claim the problem is from my end but judging by the reviews here it is quite obviously a complete failure in their part to keep their service aggreemments, if there is any. I have a limited time to carry out my application and nobody is assisting properly. So frustrating that such an important service is being *********** ly run. I ahve emailed and called constantly and now don't get any response at all. Is this just another ****?? All I want is an appointment, that's all. I have down my end of the deal when will they do theirs?
