Afrihost Data Dissapeared in less than 24hrs

On the 1st of every month I receive 2 Gigs of data from Afrihost and they bill me upfront for it. 1st of January was a holiday and I was on Wi-Fi at home the whole day. 2nd of Jan 2019 on my way to work I realized that I did not have data and had to re-load. When I called Afrihost, the Consultant checked and agreed with me that it was not realistic that my data would be finished in less than 24 hrs. He also confirmed that Afrihost just picked up a system problem and were working on it and would refund the affected Customers. I have been waiting ever since. Today 21st I called again, and the Consultant told me a different story and actually told me that in less than 24 hrs my phone finished 2 gigs of data. I have no twitter, Instagram and do not watch movies on my phone. On top of that... I have Wi-Fi at home through them, and on the 1st Jan I was on Wi-Fi the whole day. Calls are recorded and I want them to listen to my 1st call and hear what the other Consultant said to me. For the 1st time I feel ****** by Afrihost and considering moving if this is not resolved.
