Poor customer service and billing

If I could give a 0 rating I would. After being quoted and paying for the required work, labour and parts, the technician arrived on time as was brilliant. The challenge came when, the technician was finished in half the time quoted and the parts quoted for R1000 was only some insulating tape and solder wire. I immediately contacted the call centre by mail and phone, was told that the managers were all in a meeting and somebody would call me back shortly. After 2 hours with no response I again sent mails and phone calls and was told I would be contacted. This was on a Friday, so assuming as it was weekend that first thing Monday morning I would be contacted. After no contact on Monday morning I sent a mail requesting information, to no avail. I then called again spoke to the manager who proceeded to inform me that even though only half the time quoted and paid for was used there would be no refund and that he would "look into" the parts refund, as he was not aware of the situation. The technician, Mandla, was great and his work superb. The manager told me if the work was done and if I was happy with the outcome then I must accept that and be happy. If you are going to use this company ensure you get a full breakdown of parts and labour before paying and ensure these are met, beacuse strahely enough if the technician sees he is going to run over time by a certain amount or additional parts are required, you will need to be quoted again and payment made before the job will be completed.
