Disappointed with the service

On the 18th December, I called the online department to check which store has the 3x tops i wanted. All the tops were at the Durban CBD store. I called back to check what is the process to transfer the tops to the nearest branch. Sive, call centre agent, assisted me with the fashion delivery. She was very helpful and went through the whole process with me. I was advised that there will only be ONE charge of R40 as all the tops were at one branch. I had a voucher - R150 off R750 and the total was more than R750 so i was able to use the voucher. I was also told that i will be informed before any chargers go through my account. She advised me that i could also call the store and ask them to keep the tops aside until they receive the fashion delivery documents which i did. Nmondi at the store left the tops with the fashion delivery department. I gave her the reference numbers and my details. I received a call from someone on the 21st stating that she had selected my tops. I advised her that the store had kept them aside for me. She told me she would call the store and call me back. I didn't receive any other calls from anyone at Truworths again. On the 28th, I called in to find out when the tops will be sent to the nearest store and the lady put through an enquiry. I got a call on the 31st stating my the tops are at the Gateway store. I went in the next day to fetch them, only to find that the tops were all charged separately, I was charged R40 delivery for each top and no voucher was used. I am very disappointed with this as it costed me R230 more where as if i was informed correctly, i could have fetched the tops from the CBD store myself. The manager at Gateway was very helpful and she called the online department and asked them to call me to rectify this but no1 has called me since. I would appreciate it someone gets back to me.
