bouble debit transaction entry online

this is now annoying, every time when I buy online with Woolworths this bank debits twice the amount and im getting tired of calling this people and unhelpful call center wasting my airtime , last week I bought for r150 twice =r300 and they debited r450. I even received the order I bought as money reflected on their side(Woolworths) , can you stop with thing of yours putting it on budget and return my r150 back into my account now. and other day trying to buy 8ta airtime and it didn't recharge by my r12 was taken twice then on 2 was returned, return my r12 back into my account. this is very disappointing and annoying , stop wasting my airtime.

thinking of even closing this account is stressing me now, and its enough.
