New decoder proposal

My grandmother received a first call from Qaqamba proposing an upgrade on the decoder and they did the whole procedure and she advised a decoder will be delivered in the next 7 days, nothing was delivered Then just now a call comes through from Zama who was rude called for the same proposal. I took the call as I felt she was not respectful and speaking in a good manner with my grandmother, I asked if their system doesn't show its the second call that was made to the same person with the same proposal, she then said she will give the phone to her manager which the request was not even made to speak to her manager, afterwe waited for the manager she advised she wants to double check on her system, then she came back to say the skylight people tried calling my grandmother to no avail, which is strange because no missed calls from those people and I believe that those people who have called the consultants back to advise they are not getting through to the client ,then again she says she will give the phone to the manager I then advised we are not interested anymore because I feel like it's a **** and no manager came to the phone
