Horrible service, paying for something we are not getting

I called in Yesterday to request for my account to be reactivated as I had paid my bill because they fail to debit means per agreed, the lady informed me to call the billing department...I contact them today at 13h00 they confirm receiving my payment and that my phone should be reactivated within 4 hours till now the SIM card has not been activated...I cannot call nor receive calls even though I paid more than I should have.... Very poor services I am asked the lady to debit my account on the last day of each month yet the app reflects the 3rd of each month.....very poor service, will be escalating this matter to the relevant regulatory board. I went to the website and to look for an email to address my concerns no complaints email posted.
