An apology is always a good thing. I have to agree with noswal though that discounts for "no service days" would be very welcome. Unfortunately the South African telecoms landscape is structured in such a stupid manner that sometimes service providers cannot be faulted for "no service days" and cannot afford to discount customers.
Need we say more? I think people should still insist upon discounts because it will keep the pressure on people who can relay the pressure to the people who hurt us.
This is one of the reasons we cannot lay off the poor Telkom call centre people. We have to be polite but firm, always. Keep the pressure on them and they will pass the heat on to their superiors in due course. This goes for all the call centres of all the business in our telecoms industry. Apply customer pressure but always be polite. Polite until you cannot be polite no more.
