Poor service on electri blanket replacement

I awaiting now already 4weeks to have a replacement Ecnoheat electric blanket. The second week I already start phone. The manager in the repair dept did no phone me back during many acaution. Last week Sunday I went to the shop to speak to a Senior, they then called Mr Notes. On Tuesday I called the shop again and ask speak to the General manager, Mr Deysel say he did know anything about my problem but he will come back to me which did. I only received a call on Friday from the repair dept manager but she still can't tell me when I will receive my blanket because she is waiting for a proforma invoice from Econoheat. she can't gel me I will receive my blanket. Did tell her I will now go HELLO PETER her reply was I can go. Makro don't bay any Econoheat blankets any more.
