Fibre cost doubled without notice

In April Afrihost debit my account almost double what they normally do. When looking into it my fibre price just under doubled in cost. When queried, they apologize, did a credit note. This month again, the same thing happens.

The difference is that now there is a sense of attitude in all my responses as if I am some idiot that doesn't understand. My fibre cost is now just short of double of what it was. Apparently as per them "50GB 100Mbps Vuma Aerial Fibre R567.00 (per 1 month) until 2019-07-01 got expired and right now you have been charged R1,117.00 (per 1 month)"

So I was never informed of this, nor did I know my package could expire and they force me to pay double the money for the same service. I expected a reasonable annual increase as with any other service or service provider in the country.

I am not impressed Afrihost. I used to sing your praise and sent many many customers to you both from a business and home usage side. And now you drop the ball like this.

Fix this !!!
