I recently went for the deal here on HUKD for the £39.99 3 Huawei U7510 at Argos.
I topped up £10 and managed to get the freebies as per the 3 PAYG tariff (150MB internet, 300 txts, free 3 to 3 calls).
Over the festive period I have used up all the internet and the £8.56 of the cash credit. I topped up a further £10 but all 3 has given me is the £10 cash credit with no entitlements. When I check my 3 Pay balance info on the My3 page it shows the free allowances as per the 1st top up ... (i.e. the free 3 to 3 calls expiring on 24 Mar 10 and the 200+ 'free' txt messages I have left.
I thought that each top up extends the allowances .... just wondering whether anyone else had the same issues and how they resolved them ... I understand that CS is a nighmare!
