Bad Service Again!!!

On August 1 an amount of R895 was taken off my Bank Account...I have just upgraded my phone with great difficulty as per my previous contact with you...and now have this huge amount deducted instead of the R213 that should have covered my new phone contract..I called Vodacom and spoke to Winnie Mazibuko who escalated the query for me...she mentioned that it would take 7 days to resolve..however I have checked on my Vodacom App and on Vodacom chat and the query has not even been allocated to anyone as yet...In the meantime I have received messages from Vodacom Customer Care informing me that a further R386 will be deducted from my account on the 3rd of September..when I dial 082135 I get through to a recording...No one has responded to any of my attempts to find out when this amount will be refunded to me as well as to stop the R386 from bring deducted in September...I am a Pensioner on a limited budget and cannot have these amounts just taken off my account..As no one is particularly interested in my query ..I am at a loss as to where to turn...I have gone onto Vodacom chat several times and have emailed Winnie for assistance but have not received a response...Pleas see below..Your query has been escalated to one of our Solution Experts. Your ref number is: 1- ********** ********** Visit www.vodacom.co.za/app from your phone. Thank you, Vodacom [Service RequestOwner Group]
