Shocking customer care

Be warned if you are planning on signing a lease agreement with IHS property management. This has definitely been one of my worst experiences regarding customer account management. Dealt with Pieter and Michael from IHS for the past three years. Pieter has no sense of customer or account management. Plain rude with no accountability at all. Ignores mails and cellphone calls. Also has no problem with being rude to clients or throwing his own junior co-workers under the bus for IHS mistakes and flaws that were caused by him. My invoices are never the right amount and somehow there are ALWAYS some unexplained water and sewer charges which differs from month to month depending on how IHS feels ( we have actually tested this when we were away for the majority of the month and used buckets when showering to save water). Lately I have been dealing with Michael who is professional when I reach him but he almost never answers the phone and doesn't return calls either. Also takes weeks to respond to mails. Absolutely shocking client management.
