Bond Switch to Nedbank? No service from FNB Homeloans!

Ive emailed, made applications and called Home Loans several times, yet almost 4 weeks later, I am no further advanced and nobody gets back to one. I spoke to Philisiwe Mvubu day before yesterday, who said that I should drop the call such that she can call me back.. to date she has not done so, despite the urgency of the matter. Yesterday morning I spoke to Khageeso, who said that he would either have someone call me back within 15 minutes, or assist me personally. I have not heard back from him since then! Later yesterday afternoon, I spent at least 30 mins on a chat with Home Loans via my banking app, again being promised that the matter would be escalated and that someone would get back to me as a matter of importance. After depleting my energy, my time, as well as resources such as airtime and data, my query remains unresolved! Service delivery is pathetic. The lack of respect for consumers leaves much to be desired! Do we as consumers, actually even matter at all to these large corporations? At least enough for them to just honor their word when making promises to clients.... promises as simple as simply returning their calls, thereby respecting the efforts that we make to manage our affairs! So very disheartening! Perhaps time for a change of banking institution! So frustrating!
