Telkom must get their act together they've already been on the TV for their ******* act

I hve a mobile contract with telkom I pay them every month never skip a payment, the very 1st month they hve the wrong banking details, I fixed and paid at shoprite, I asked to cancel debit order I'll pay manual, they still deducted from my banking account, in August they msg me debit failed I went to different telkom stations they log calls and I spoke to different click a call agents, I paid my account at abs now never skipped a payment I keep getting msgs I'm.in arears, now my contract been disrupted I can't use my phone I mst pay then r830 before they will connect me again but I never skipped a payment. I went in to different telkom shops explained my situation still they find a problem with me when it's clearly their side. They changed my payments dates I don't know how many times when it supposed to be for the 15th of every month and I pay them every month by the 7th. I'm so frustrated with telkom and won't ever sign up with them for anything and I'll advise all my family members and friends not too. Telkom a very bad service provider and I feel the ******* poor people that really just want to be mobile. I thank you
