stop passing the buck keep to a promise

I made an online purchase on the deal of the day in August.I was admitted into hospital on the day they were delivering so I called in to inform them that I will contact them upon my discharge.I did contact Vodacom but they said they had cancelled the order??I was most upset as I wanted to do an upgrade and this offer suited me perfectly. To this day Vodacom has promised to get back to me but despite numerous calls empty promises,I have still not received the offer or managed to upgrade. I get the distinct impression Vodacom does not want to honour the deal.This is my second contract but my first utter dissapointment in the service I have received from a reputable company like Vodacom.If you do not want to honour the deal then give me an answer either way do not promise to get a manager to contact me but knowing full well this will not happen.STOP PASSING THE BUC****!
