VODACOM **** TO ME

In December Vodacom contacted me, and said, they can offer a MECER laptop with 5gig HUAWEI R218R router for R399, and that my two current accounts billings would be halved, due to that I am 20 years with them. They send another router again in December, that I didn't received. When my billing came in January, I saw, my billing is R500 more as promised. I contacted Vodacom, and they said, the second router that was send to me, wasn't cancelled. So I asked them to cancel, it for me. They said my account would be credited with R199, and in February I will pay the R199 also less, with the one of January. When I received my billing for February, my billing was the same as January. I contacted Vodacom again, they forwarded me a mail as proof on 13 February, promising that my credits will be paid back. When my debit order went off, the whole amount was debited. I forward a mail today the 27th of February again, and according to them, no credits will be done. Now I want to know, how can a company sell you something, promise you something, and don't hold to their side of the arrangement. When I queried the first time, they said that agent **** to me, and they cannot half my two current accounts. I said but the phone calls were recorded, and they said no it wasn't. I am really furious and don't know what to do. My only answer is to cancel all contracts after 20 years. BAD BAD BAD BAD service really, and they lie to their clients
