It is as simple as that keep that receipt.  Have you ever bought airtime and after loading it the air time is not activated due to an error arising form you just because you were in a hurry so you got a few digits wrong or there is a network error!

Have you bought items from a supermarket and on leaving the supermarket you leave your receipt with the security personnel at the exit point only to get home and discover that a few items which were bought are actually missing from your pack. To go back to the supermarket you need a receipt and it might be difficult identifying your receipt out of the many receipts with the security guard because Supermarket receipts don't have customer names.

I'm meant to understand it has not happened but I witnessed it. Recharging your DSTV account and after that you are disconnected two days later. On complaining, the service provider will demand for the receipt and should you not have it, then your case will not be helped.

In all the three examples if a receipt has been kept, there will be no problem at all but in event of the receipt missing then no help will be accorded. In the same vein if the police has recovered some stolen items and you happen to have lost similar items, the police will refer to that receipt to tell that those recovered items are yours.

This is the festive season and many people will be buying gift items. The return policy for most of these supermarkets is not clear so please keep that receipt because that will be the only way of being helped in case of any items to be returned or similar complaints.
