Pathetic Customer Service

I bought a couch from Coricraft in March 2015. In September I noticed the stitching on a seat cover was tearing. I contacted Coricraft who collected the cover & had it for a period of 2 weeks. When the cover was returned I found the tear still on the cover. I made a note of this on the delivery note and tried to contact a manager at the Rosebank store immediately, but was told that no manager was available but I would be contacted on Monday to discuss my problem. To date no-one returned my call. I went back to customer service Jhb last Monday. After hearing my complaint Fiona referred me to Bianca. After promises from Bianca that she would call me back with a solution after discussing my issue with management, no return call was forthcoming. I called Bianca again on Wednesday only to be told the same story. I then again contacted Bianca on Thursday when she arranged for the cover to be collected on Monday 12/10. On Monday when no-one came to collect the cover I called Bianca. She was to call me back but never did. When I called her again she advised of a mix-up in paperwork and arranged collection for today. Needless to say the cover is still not collected with no explanation.
