Worst customer service received!!!

Worst customer service ever received. I got double debited and had to make follow ups with call centre agents not honoring their promises, Initially I was assisted by a guy named Mali who caused all this inconvenience and at no point did he try to resolve this. After speaking to more than 5 customer care consultants a lady by the name of Megahn Hughes promised to get it resolved and promised to contact me, only to not do as she promised, it took me being angry and aggressive just to get assistance, having to fight for what is rightfully mine, no professionalism and overall service is terrible to say the least, more especially if you go the patient and understanding route you will be played with...
