Appalling customer care from management

Having made 7 moves in the last 7 years I chose H&M for the first time in March 2021 to move my household contents from JHB to CPT. The JHB team was professional and courteous and I had no issues. On the CPT end they arrived 5 hours later than notified, offloaded in such a hurry I was unable to account for the 103 items, most of which were boxed. I did my own wrapping, packing and boxing. 2 days later I discovered 2 missing boxes, one of which contained contents to the value of R40,000. It is now June, and despite 6 or 7 emails and phone calls nobody has bothered to respond except for the first instance when someone enquired as to the contents and value of the missing items - which was supp**** in detail. Since then, even following a threat of legal action, I have been met with stony silence. They also took off with all my blankets used to wrap the furniture items. I have no issue with the movers, but the management is appalling. I will not use them again under any circumstances.
