worst service provider

I ordered a RAIN 55gig + 55 gig from webafrica, in december i used 24% of my 110 gig and i was soft locked, i called webafrica and was told there an issue on IS side and they working on fixing the issue. Since december 2017 i an left with out connectivity coz webafrica did not attend to my sim problem, i was promised credits back into my account as they are debiting me every month for the service. I complain every month via support tickets and calls but get promised the problem will be sorted out and new sim issued and am still waiting . I feel you guys are a huge *******. I have been buying data from other service providers every month and its costing me a lot of money. If this is not sorted out im gonna hand it over to my attorney and SUE WEBAFRICA FOR LOSS OF BUSINESS ALSO.
