Demand refund

<p> I bought a vodacom tablet (different no. than my cellphone) with 3gig data 10/04/15 at Game. Used up the data and bought another 3gig. Then a third 3gig which dissapeared followed by another 3 gig on 20/09/16 which also dissapeared. I only use tablet when away from home. I went ballistic because its R299 for the data and its just gone. I was then informed by my daughter the same thing happend to her and she then noticed that the sms vodacom send you states that your purchase is only valid for 1 month!! I never read vodacom msg's after the sentence that informs me of the 3 gig. What a ****** cheek!! I paid for the service and i want to use it until the full 3gig is used up. It is totally ridiculous to place a time limit on a purchase of such a commodity a data. This is blatently unfair and ************ and i am sure against the Consumer Act. I DEMAND A REFUND for R600.00 worth of date purchased and for which i never had the benefit. To top it all on Sunday i get a sms at 4 o clock in the morning and another at 6 oclock in the morning wanting to know if i will recommend Vodacom to anyone. Is it in your best interest to disturbed someone while they are sleeping?? Nevermind the absolute rudeness and inconsiderate sms waking up your client!! Refund my date usage or a complaint will be laid at the consumer council and then i will forthwith change my service provider for my cellphone as well as purchase another tablet from a different service provider which have fair business dealings with their customer.</p>
