Bad Service

We where involved in a smash and grab. On Monday 16th of March we went to PG Glass in Centurion to report it. We where advised that all is fine they o will call us in a few days to have us come in to fit the window. After waiting and waiting no one called us. I called on Friday the 20th of March just to be told oh sorry we don't have stock of this window. That already made me so angry as I had to call them. We where then called to advise oh we can come Tuesday the 24th of March. My husband took a day off at work to sort it out only to be kept waiting the whole day and after various calls again to them be told oh sorry the person that needs to sign the cheques is not there. Then my husband was told they will come to his office to fit the window. Cool very happy that this will finally be sorted we where told oh they cant fit it as the mechanism that moves the window up and down was broken on the inside. Now please tell me as a company that specialises in windows are you not suppose to check all areas to make sure that the window will be able to fit. Now we where told another 2 to 3 days if stock is available if not then 3 weeks. THIS IS UNACCEPTABLE. I NEED THIS SORTED ASAP.
