Worst service ever. Blatant theft!

This stems from a data provision issue that I reported in Nov 2018. I have exhausted all possible measures provided by MTN with various agents and reference number to calls logged. MTN continues to deduct funds without crediting me with the data billed for. MTN has guarded themselves with hoops and red tape, automated call centers give you the run around and sends you from Arthur to Martha. Conveniently sending sms notifications of a speedy resolution without outcome. Agents simply “escalate” matters passing the buck and still no outcome. Store agents escalation also bares no fruit and still I am billed for data which is not allocated. Surely there has got to be recourse. This is ludicrous ????????
