Bad service, ignoring clients!

I've been waiting for feedback since last week Wednesday from their consultants on WhatsApp and they have been ignoring me, this is after I queried why they would say I have cover and the next thing say the cover is suspended after they assured me that they debiting early because its December and that their next debit will be 30 January, instead of solving the query and giving feedback , they have since ignored me and I've followed up numerous times and gave them an opportunity to resolve , I'm concerned on how they do business, no accountability at all .
