Telkom online contract

I have app**** for a Macbook Pro on Telkom's online store and was promptly phoned in 24hours. On approval of this contract they had no stock available to send out to me. The consultant said he'll phone me back in 10min. It was 8hours later and another consultant phoned me. I explained the story of no stock and once more they said we'll get back to you. 4 days passed and a lady contacted me to ask if all was well with the purchase? I said, well, it would be nice if I had it or that someone woyld phone me back and then the line was dropped... No surprise there! I then tried to contact them (Telkom) on ********** 939 and 081128 but with no luck, either the automated systems stops working and drops the call or the person tells me that she cant help as the online sales centre does not have a incoming call number. So what does a person do? Should I give up? They need to do something about this as I still get sms's stating that they tried to call me (with no missed calls on phone) and they will get back to me or try later. This happens every day or so. It would be great if someone could just give a call and say... We are here to resolve the issue.
