Really disappointed

I would just like to make it known how dissatisfied i am with the service im receiving from FNB. I have been querying a pending payment since the 25th May. I order something online at spar on the day of the 25th May. I noticed that the payment was deducted twice from my account when i only had 1 order. Few days later the payment for the initial order has gone through and now the other payment for the same amount is still pending from the 25th May. I have been in contact with Fnb and was told the funds will be reversed in 24-48 hours, guess what? The payment is still pending. There is bo dispute with the merchant and i do not have proof of any communication with the merchant as i called them. The money belongs to me as Spar momey had already gone through ti them. I then logged a dispute as i was informed by webchat advisors, i did this once and was sent aml other email to do exactly thr same thing that i done before. I am not getti g any assistance from fnb which les me to come here to grieve. Fnb would not even attempt to call me to find out what the problem is instead they sending me emails which i am compliant with and still no proper feedback. I do not understand what needs to be investigated because the merchant has their money but now i have to fight for MY money which is currently still pending. Can someone from fnb please assist me with this request and please do not tell me to follow the dispute process because i have done that. The money belongs to me and i do not owe the merchant sk why is it so hard for My money to be reversed back into my account as the payment clearly was not suppose to be deducted from my account since i only placed 1 order. In addition to all of this i hd loan accounts with fnb which i have settled in full, only yo find out these accounts ate not closed and now interest is being charged. I tried closing these accounts on the app but to my surprise there is a settlement amount which i think is not suppose to be there because i have paid the settlement amount that was given to me on the app. A webchat advisior once again told me they will log an account closure request that take 5-7 working days, the SLA has lapsed and guess what, those accounts are still on my profile. This is causing a negative reflection on my ITC and demand that this be rectified.
