Registry complaint

We used Mr Price home exclusively for our wedding registry and our guests are unable to access it. Our guests are going out of their way to buy a gift only to be told there is an error. Apparently the gifts are also not taken off when bought so there will be duplicates? Mr Price also does not inform customers that online registries can't be edited in store and about delivery fees. I have seen this complaint dated back to 2012 and it's still not resolved. The amount of complaints on Facebook is shocking. I really hope this can be sorted out, and would really appreciate your assistance. Thank you.
