Mweb and Evotel Shame on you!

I have fibre with Evotel with the Isp as Mweb, I canceled my Mweb on the 1st August with last day of coverage on the 31st at 12 midnight The new isp contract will then start at 12am on 1 Sept, Mweb deducted there premium and today no fibre call Mweb it's not them it's Evotel, call Evotel same story so i paid and now I have no connectivity This is the worst service I have experience How will this be resolved? My connectivity needs to be restored ASAP. If not connected soon I will have no alternative but to reverse the month fee in order to ensure connectivity somewhere else!
