Over promise and under deliver, WORST SERVICE

It is with utter disgust that I have to log a complaint just to hear back from Vodacom, it has been more than a month since we dropped off the phone at the Vodacom N1 City for them to repair a cracked screen that was bough lessthan a month ago prior to the phone being damaged. A month later we still waiting for the phone. At the point of purchase we were told that the phonedis guranteed to be fixed free of charge should the screen be cracked. VERBAL AGREEMENT and this is what I expect as a customer for the phone to be fixed and ready for pickup, no later than Friday 22nd May , this takes way too long.. I call the store and promises are made that Verna will call me back, but no calls. I need this to be resolved. Please contact me. I would appreciate a prompt response.
