No feedback from Customer care

I logged a call on 30 March with the Vodacom customer care centre because I cant access myvodacom and for some reason I am no longer receiving my statement electronically or in the mail and it has been extremely high even though I moved to a cheaper package.<br> <br> On the same day Arafat Nokhemane sent me a reply that they have escalated the query to their back office who would contact me within 48-72 working hours.<br> <br> I tried to follow up on the 5th of April and until today I have not received any response and no one has tried to contact me to resolve this.<br> <br> POOR customer service to say the least.
