I found Vivek to be super helpful, efficient and pleasant to deal with. However, the call centre was a different story. I was not impressed. They couldn't give me a time only that he would be there between 8am and 12pm. I told them I had to leave at 11am so they said they'd book me as the first appointment, shortly after 8am. They didn't pass on, I had to leave at 11am. He had a meeting that morning that was scheduled and they knew about, When he did ring it was too late. I wasted a whole morning. You have to be able to book a time. Saying, sometime in the morning is not good enough.
