I got a thicker glossy brochure that said the same, the rebate is unused units not unused money spent. I complained, and was told the advert/leaflet was not the 'formal' price list, and that explained the actual rules. However, the calling card had the impact that each 5p I spent reduced the rebate as one unit, and not each 'unit' I spent (remember the calling card charges 10p/unit not 5p/unit). As this meant some usage then the light user scheme rebate was impacted by my calling card usage. As such I benefited from the light user scheme.īit I did, occasionally, use my BT calling card.

It meant that most actual calls were made with a prefix and a code and charged by Mercury and not BT. The fun thing was that calls from my home phone line were circa 5p per unit, and calls using BT calling card were circa 10p per unit, both on my home phone bill. I did decode that once using calling party clear calls to the payphone. That itself was fun, as the payphone sent a DTMF sequence reporting its number and you could hear it do that. I also had a BT calling card allowing you to enter a long code on a phone box to make a call on your home phone bill. I had a phone line, and back then I was living seriously on a budget. I remember those days, BT was simple to deal with, and they had sensible compensation for faults. It was the 'social' tariff of the day as there were no 'call bundles' or crap like that. It meant those not making any calls, or few calls, got line rental at a much lower level. This was a totally automatic system which meant that if you used below a certain number of call 'units' in a month you got an automatic discount per unused unit off your line rental. When BT were the only telco in the UK, one of the things they had was a light user scheme.
