Just Nothing.

In August last year I received an sms notifying me that Telkom was going to replace my landline with a mobile device and that I would be contacted for delivery of the device. In September I received a call confirming my delivery address during office hours, I travel frequently and they can only deliver the device to my house (no one at home during office hours) or to my office but I must be personally available to sign for it, no problem what day? They cannot tell me that just that it should take place over the next two months, three and a bit months later and nothing, no calls, no device just nothing.
