Appliances that has not been repaired or replaced

Products have been reported faulty and collected approximately 1 month ago, up until now, no feedback has been given other that a call to collect the products 2 weeks ago, not knowing that it has already been collected, the person who called could not even tell me the status of the repairs that has been done and still today 04/06/2015, i have now decided that i do not want these products back and replaced with new ones ASAP, my account has been debited for appliances that are not in use, this is unacceptable!!!
