I app**** for a home dstv explora package. I was advised that I can get it installed for a fee and also my numbers will be swaped or ported as it came with an attractive cell phone package. I also app**** for an extension. It has been 3 weeks and I continously get **** to!! No one takes responsibility and everybody blames everybody else! I want to cancel this contract now as I haven't even attained my package yet and am literally having hell. Apart from promise after promise that someone will come and install to do the extension , wifi and dstv.. I was also advised that he would bring nano sims as the wrong some were delivered. I then asked if I couldn't go in and do the swop for my number and get the sims cause it was taking too. And was said by afew consultants to.. I went and again was advised my telkom direct south gate that whoever did my application did it wrong upfront and they can't port our numbers!! We use these numbers for business so if that can't happen then I might as well cancel the deal.. I still don't have wifi or the dstv or the sim cards and I have already paid for the month!! That's not right and breach of contract from your side!! No integrity displayed!
