Black Friday special *****

I spoke to the sales consultant over the phone and he told me I must come in for the black friday deal that is R99 per month for 6 months.

Came there then he informed me, no head office phoned this morning and said it is only going to be for 4 months, the tbe contract is going over to normal amount of R649 per month.

I said it is ok and I took the deal. It is now month 4 and they took R649 x 2 because me ans my wife joined. I phoned head office and they told me, the special is now just for 3 months.

Somebody is lying here. I want it to be correct for this month please.
