Waiting months for cash back on HealthyGear

I bought goods in TotalSports on 31 January, before the new HealthyGear rules came into effect on 1 February. When I didn't receive my 25% cash back, I contacted Discovery Card on 18 February and was eventually referred to the Vitality section on 7 March. Then they insisted that I have to provide proof that my HealthyGear card was swiped, which I provided to them (on 31 March) after a lot of trouble (bearing in mind that the transaction took place on 31 January). Since then I have been given excuse upon excuse why it is taking so long to resolve my query.<br> <br> Also, this is not the first time that I have had to waste a disproportionate amount of time to prove to Discovery Vitality that their systems get things wrong. Not impressed.
