Unexceptional service

I have purchased a voucher on hyperli, I called and book for 4pm, and I arrived an hour later, when making the booking I was not advised that the last intake is 4pm, when I arrived not even the manager accommodated us, she kept on making excuses about how the booking office was supposed to tell us that the last intake was at 4pm, I called the following number : ********** from 15:00 to 16:10 to reschedule the time as I was running late and there was no answer and Thami Dywili, couldn't even assist instead of her accommodating us for even 1 session instead of the four sessions all she did was blame the booking department and how they all need to knock off at 18:00 I feel that her as a manager she doesn't know a single thing about customer care and all she was saying is how tired the ppl are, I will never visit Acrobranch Melrose again
