Pathetic

I have been with Vodacom for 20 years. Supposed to be one of the priority clients. I was promised to receive a voucher with my upgrade. I upgraded in November and was promised to receive voucher on 15 December. Every time there was another excuse. I was then told it will be on 16 December, then on 21 December and now they confirm that it will only be received on 2 January. And I will phone on 4 January and get an new excuse for sure. And every time I phoned another number was given that was supposedly to assist me with my query, and they couldn't. Not one person's story is the same as the previous one. I am fed up with this company, all they do is lie. I will definitely be cancelling my contract as soon as possible.
