Telkom Mobile - Breach of contract, pathetic service, no values and principals

The most pathetic service provider who do not stick to principals and legal documents!!! Jabulile Malete ********** is the most useless team leader and the billing department Charlene Mncube ********** Jabulile gets all the legal and signed information regarding my contract upgrade and did nothing about it. The contract was signed with a R0.00 limit the day I took my phone. More than 6 weeks later 100s of calls and emails done. Time wasted on these people with no sense of customer service. I received a call from Charlene Mncube who advised that everything will be done on her side within minutes. It was an error on their side as it was signed even though the date on the document stated 10/07/2018 the actual date and signature was done on the 10/05/2018. They will refund the extra charge and adjust my debit order for the end of the month. Today I received an email from Charlene. after more calls and emails requesting an update in writing. She advised that what she advised on the phone and gave me her word that she would do will not be done!!! Extremely disappointed after being a customer with Telkom for more than 8 years. This is the type of service that you will receive no matter who you are as this is the norm for them. I cannot believe that this company can even behave they way they do with *********** people working for them. Charlene refuses to send me the voice recording of the conversation but have 2 witnesses as I had her on connected to my car radio. I am definitely going to take this further as this company lacks principals, values and clearly customer service #Telkommustfall . Anyone know the quickest way to take them up legally???
