Vodacom Service, Network etc a Disgrace

I opened my number for international roaming, then within 5 WhatsApps and a 3 minute call, my bill went from R1110 to Over R5000. When I landed in SA on Thursday 13th June, they told me I must pay R4680 in order for the phone to be opened. I paid it immediately and I was told it will take 2 hours to open. Today is Sunday and the phone is still not working. Nobody can assist you and all they say is reset your phone or we will log it in. Now I phone 5 minutes again and there is a log that has been logged and I will receive feedback on the 21st June. Vodacom wants you to pay a monthly bill even though you have had no use of your number what so ever. Nobody can solve the problem. Then to cancel your contract that you have to pay an upfront hefty amount before you cancel. Vodacom has no customer service at all. Their service, network, everything has gone down the drain. I have been a loyal customer over 20 years now will the same number. They want your money but can not assist with anything. When you ask for a manager, a manager cannot even take your call. It is a disgrace. Call Centre people are not helpful at all and do not care if your number is active or not, too laid back, it is a disgrace of how customer service does not exist. Whatever happened to the customer being first. I refuse to pay my bill this month and will look for another network provider to move to as Vodacom has no service.
