Vodacom is pathetic!!!!

Last year October I switched from FNB to Investec meaning that my debit order is going to be stopped, I infromed Vodacom and they told me that I should just pay via EFT for the next three months and then the debit order will automatically stop! Did that, R650 in penalty fees further, I payed everything including those penalty fees even though I shouldn't have!! Now EVERY month they suspend my account and I have to call them every half hour to ask to activate it again with no success!!!! EVERY single month I do my payments and send the proof of payment to ********** and still they suspend it!!! VODACOM YOU ARE PATHETIC AND I WILL NEVER RENEW OR GET A NEW CONTRATC WITH YOU AGAIN!!!!!
