Total lack of customer service from management

Traditionally I always have glass of French Champagne at my birthday breakfast. My husband called ahead to Doppio Befordview to check if they serve champagne by the glass, was advised not, so we took a bottle of Moet - from which I only had 2 glasses from the whole bottle. Firstly glasses were filthy - orange sediment stuck to inside - then charged R100 corkage - which the waiter did not advise us. Asked for manager. He ignored the request, finally we had to walk over to the owner as know him well after 20 + visits, he had seen there was a problem at our table but also chose to ignore us. He advised it's standard policy to charge corkage - not the first time I'm eating out, so aware of that - however they were unable to supply champagne by the glass and he added that legally not allowed to serve alcohol before 10am - this was 9am. So not revenue they would have received anyway - yet he justified charging R100 - not the money that's the issue but the principle. To add insult, didn't even wish me a happy birthday. Clearly they don't value their customers.
