Pathetic service and Lies

I have been a customer of Vodacom for just about 5 years. I am so disappointed in the service that I have been receiving lately. I had 2 lines that I took out on contract, one of which was expiring in August this year. I called Vodacom to give notice that i want to cancel the contract and convert the number to prepaid. To my surprise i am still being debited for the line that i requested cancellation. i have been struggling to get my refund for the 3 months debit order they took. everytime i call i get a different story. first i was told that te refund takes 7 working days. after a week when i inquire i am told that the line was never cancelled and i must provide proof that i did cancel. i tell them that had i known that i need to keep records of my interaction with Vodacom since i assume that they are professional and they know what they are doing. each time i am promised i will get a call but nothing ever happens. each time i follow up i am told that the person i spoke to the previous time did not do what they had promised to do. i would caution anyone who is considering taking a contract with Vodacom. i have never been late with their payment in the 10 years and they refuse to refund me what is rightfully mine. pathetic.
