Waiting for Makro to respond

I ordered an AEG gas hob online from Makro on Monday 26 Nov. Payment was processed. Collection date was given as 7 to 10 calendar days from purchase date. I checked this morning on the website to discover that collection date had been changed to 40 calendar days. Obviously Makro took my payment without having sufficient stocks of the product. I tried twice this morning to get some sense out of the people at the Makro call centre. They were clueless and could not call a supervisor as they were in a meeting. Am still waiting to have the matter resolved. Are you happy with this customer service Mr Hayward ?
