Poor Poor Service

I have contacted Vodacom multiple times regarding cancellation as their prices is ridiculously expensive on phones. First they stated they cannot assist me, second time I phoned again spoke to Mr. Nelson and he stated I must send him snippets of the prices from other providers via email and he will get back to me since today he did not respond and it is more than a week now. I phoned again spoke to Mr. Pillay and he only stated I must wait for Nelsons response without even trying to assist.
