Telkom bad service !!!!!!done with them

I’ve been a customer since 2015 ,and lately it’s just been a disappointment. So Telkom was suppose to deduct a R690 last month . Due to a credit on my account . They ended up deducting the normal R2053 . I then phoned in and a lady said they can return the money back into my account within 7-10 working days . I sent my banking details and everything . She confirmed it has been processed . 10 days passed yesterday I called in the first consultant told me it was never processed it’s now laying as a credit on my account and they can’t return the money as it’s too late and she hung up the phone . The next consultant said the supervisor named Paul will contact me , he still never contacted me . Called again today the first consultant put me on mute the entire time , second consultant also it just went dead . I’m tired and I needed that money , they take me for a joke . I’m at that point where I’m done with Telkom !! And if I do a reversal on my side they still going to charge me a R220 debit order fee . But they the wrong ones for deducting way more than what was said .
