Is covid makes some business totally pathetic service ...Just a call and been honest

To whom it may concern , I ordered on line and generally it is around five days for delivery . This time I ,yes I must call them to find out where is my delivery .I do not leave home just not to waste their time waiting for us .Now it has gone too far .My last call and requested a manager because I was promise a call this 16-04 BUT no calls and they did not even had the courtesy to call me back or better promising to get a manager to call back within five or ten minutes . I DO not understand the total lack of service .I understand I am not the only customer but charging me extra for the delivery and I must "run" after them ...call them without NO official delivery date and or time ??????????????????????? I know I should blame your courier but YOU are doing business with them .If you get lot's of complains with delivery ...Get somebody else .
