Pathetic service from vodacom

Vodacoms service from customer care retentions billing is absolutely pathetic. My line was upgrade last year end of oct but the router was not working i took it to the store and they couldn't help me. I called vodacom bk after making 15 calls to get the line to work to come collect and cancel my line within 3 days. The router was collected. Cancelation was not done yet they was taking my money every month. The agents are absolutely *********** and useless. They have not resolved my issue to date and no credit is being done. Today alone I made 10 calls no help. I will never recommend them as a service provider to anyone.
