Bad service to clients

I have been a multi choice customers for many many years. In December they advertised the special for an explora for R799 for subscription and the decoder and the price would not change for the next 2 years. In January I called endlessly and send an endless amount of sms cause I was interested and wanted to get one. Alas no one came back to me so I gave up. Today, 26th June I received a phone call from Multi Choice offering me the explora but at a higher price of R849.00. Imagine that at a much higher price - no thank you I am not interested - I think that this was a whole **** - delay getting to customers and then offer at a much higher price - I would be ashamed Multichoice.
