Complain

In April I was contacted by Mobile Plus on behalf of MTN for an upgrade, even though I don't trust these companies I agreed to upgrade as my son has lost his tablet and using it for school, now I found out that Mtn is debiting me for R185 and mobile plus for R179, called mtn was referred to mobile plus, sent email to mobile plus, was told it was value added services I must contact another company, I refused and asked for the recording where I agreed to the VAS. I sent the first email on the 6th October, second one requesting the recording on the 8th October, Jocelyn Bennie is the person I spoke to, recording not received up to now, I want my money back from April
